A custom concession settlement platform costs $75,000 to $450,000, and the driver that moves the number most is the variety of commercial structures in your contracts, not how many partners you host. Two hundred partners on four structures is a straightforward build, because four calculation chains cover the estate. Forty partners on twenty structures, with sliding scales, minimum guarantee against percentage, category rates inside a single partner, seasonal pop up terms and amortised fit out contributions, is a materially larger and slower project on a fraction of the turnover.
The bands a concession settlement build falls into
Three shapes recur among department stores, malls, airport retailers and travel operators.
The narrow build is attribution and commission only: the partner and contract model sitting above the point of sale (POS) hierarchy with dated mapping rules, sales attributed correctly including the awkward transaction types, and a settlement chain a partner can read from turnover through deductions to net payable. In our delivery experience that runs $45,000 to $85,000 in 8 to 12 weeks, and it produces a statement rather than an invoice.
The focused first release adds self billed invoice generation with its own sequence, immutability and credit note correction, plus posting into your general ledger. That is $75,000 to $160,000 and 12 to 18 weeks.
The full platform adds partner owned stock with movements and shrink allocation per contract, a partner portal with dispute workflow tied to specific lines, marketing levies and card fee recharges, fit out amortisation, and multi entity or multi currency handling. That runs $180,000 to $450,000 phased over 8 to 12 months.
What drives a concession build up
- Contract term variety. The dominant driver. Every distinct structure is a calculation chain with its own edge cases and its own test suite, and the awkward ones are the negotiated ones: minimum guarantee or percentage whichever is greater, sliding scales with monthly reset, and category rates within one partner.
- Point of sale data quality. A modern platform with a clean transaction level interface is one project. An older estate that gives you a nightly flat file with limited line detail is another, because you have to reconstruct what the file omits.
- Partner owned stock. Close to a second project. Receipts into your building that are not receipts into your inventory, transfers between stores, returns to the partner, counts performed by your staff on someone else's assets, and shrink allocated by a clause negotiated differently with every brand.
- Multiple jurisdictions. Common in airport and travel retail, and it means separate tax treatment per site plus partners registered elsewhere.
- Brands trading under two models. The same partner on concession in one store group and wholesale in another. Model the relationship rather than the brand, or you will double count.
- Loyalty and gift card interaction. Who funds a discount and who receives the cash from a gift card sold in one period and redeemed in another are contract questions the till answers by default, usually wrongly.
What keeps the number down
- One commercial model first. Settle your standard percentage of turnover partners and leave minimum guarantee and category rate partners on the existing process for a phase. That is usually most of your partner count and the least of your complexity.
- Do the contract audit before scoping. Reading every agreement and confirming the live terms is work you pay for either way. Doing it first means you scope against reality rather than against a folder.
- Statement before invoice. A defensible statement that partners accept solves the commercial problem. Self billing solves the accounting problem and can follow one phase later.
- Portal after accuracy. Partners value an accurate statement first. A portal on top of a calculation nobody trusts multiplies queries rather than reducing them.
- Leave stock to phase two. Unless shrink is currently a live commercial dispute, partner owned inventory can wait.
A worked example that adds up
A department store group hosting 180 concession partners across eleven stores, with four distinct contract structures and a point of sale platform exposing transaction level data, commissioned a focused first release.
- Discovery plus contract audit across 180 agreements and their amendment letters: $16,000
- Partner and contract model with dated, typed terms sitting above the till hierarchy: $28,000
- Transaction ingestion and attribution mapping with effective dates: $26,000
- Classifier for cross store returns, cross partner exchanges, gift card redemption and funded discounts: $22,000
- Commission engine covering four structures with the tier applied and shown: $24,000
- Self billed invoice: own sequence, immutable once issued, credit note correction, tax per partner: $20,000
- General ledger posting with the finance analysis dimensions: $10,000
- Two parallel settlement cycles and user acceptance: $12,000
That totals $158,000 over seventeen weeks. The contract audit at $16,000 was the line the board questioned and the line that saved the project. It surfaced that signed terms, amendment letters and what finance had been applying had drifted apart on a meaningful number of partners, which is a commercial conversation you want before configuration rather than after a partner receives a statement built on the wrong rate.
How the spend phases
Discovery and the contract audit take three to four weeks and about 10 percent, higher than most categories because reading agreements is the work. Expect to find at least one partner whose live rate nobody can trace to a signed document, and treat that as a finding rather than an embarrassment.
Core build runs weeks four to fourteen and carries roughly 60 percent. The attribution layer and the commission engine are separable and should be built in that order, because a perfect calculation on misattributed sales is worse than an approximate one on correct sales.
Parallel running takes the final three to four weeks and about 12 percent. Two complete settlement cycles, both processes, statements compared partner by partner. Every difference is either a term nobody documented or a bug, and settlement is one of the few domains where you can prove the new system before switching over, so do it.
The ongoing costs nobody quotes
Budget 15 to 20 percent of build cost per year, with one line specific to this category.
- New partner onboarding. Every new brand means terms captured, mapping created and a first settlement checked by hand. Small individually, meaningful across a season of floor changes.
- Hosting and infrastructure: $400 to $1,200 a month at this transaction volume, more if you retain line level history for several years, which you should.
- Contract change handling. Rate reviews, seasonal terms and amendment letters arrive continuously, and every one is a dated term rather than an edit.
- Point of sale changes. A till upgrade, a new store on a different version or a change to how discounts are recorded will break attribution silently unless someone owns that interface.
- Audit support. Self billed documents are accounting records with legal weight, and your auditor will trace a sample from document back to transactions. Someone produces that.
Comparing a build against your current renewal
There is no concession settlement subscription to compare against, which is the honest situation in this category. Your current cost is people and risk.
Start with the settlement cycle itself. If month end takes eight to eleven working days of a finance analyst, price that as a recurring cost and note that it produces a statement rather than an insight. Add the query handling that follows, and add the ad hoc sales figures your concessions team pulls by hand for partners between statements.
Then price the part that does not appear anywhere. When a partner disputes and the underlying commission is right but the derivation is unpresentable, the dispute is settled by goodwill. That goodwill has a value and it is being spent monthly. Across a large estate it is usually the largest number in the comparison and the one nobody has ever written down.
The final item is commercial optionality. If your commercial team has stopped offering terms they would like to offer, a tiered structure for a growing brand, a seasonal rate for a pop up, because finance cannot calculate them, that is revenue you are declining to protect a spreadsheet. That constraint is the clearest single signal that the build is due.
When buying beats building
Say the uncomfortable thing first: there is no packaged concession settlement product to point you at. That is unusual and it is why so many hosts run this in Excel. So buying here means keeping what you have and being disciplined about it.
Stay manual if you host a dozen partners on a single flat rate with no partner owned stock complications and no multi jurisdiction tax question. A maintained workbook with a documented method and a second pair of eyes each month is cheaper than any build and the risk is contained. Put the money into floor space.
Keep running settlement inside your existing retail platform if you already do so successfully. Oracle Retail, Microsoft Dynamics 365 Commerce and Aptos all hold a supplier, a department and a rate, and large hosts genuinely do run concession estates through them with journals on top. The limitation is structural rather than a defect: those platforms model goods you buy and resell, and a concession is the inverse arrangement, so the calculation tends to migrate outward into a workbook. If yours has not migrated, you do not have this problem.
Build when your settlement cycle is a multi week finance exercise, when your contracts use more than two or three commercial structures, when partners routinely dispute and you settle by goodwill, when you carry partner owned stock and shrink is an annual argument, or when you operate across jurisdictions with different self billing treatment by site.
When you are ready to turn this into a specification, Digital Heroes has delivered more than 2,000 projects with a named team you can speak to before you sign, rather than a bench you meet in month two. You can take that specification to any other firm on your shortlist.

Frequently asked questions
What is the total cost to build concession settlement software?
$45,000 to $85,000 for attribution and commission calculation producing a statement, in 8 to 12 weeks. $75,000 to $160,000 for a focused first release adding self billed invoicing and general ledger posting, in 12 to 18 weeks. $180,000 to $450,000 for a full platform with partner owned stock, shrink allocation, a partner portal, levies, recharges and multi jurisdiction handling, over 8 to 12 months.
These are Digital Heroes delivery bands, and cost tracks contract structure variety far more closely than partner count.
What does it cost to run each year?
Budget 15 to 20 percent of build cost annually. Hosting is $400 to $1,200 a month at typical concession transaction volumes, higher if you retain line level history for several years, which you should for dispute defence.
The recurring line specific to this category is new partner onboarding: terms captured, mapping created and a first settlement checked by hand. Individually small, meaningful across a season of floor changes.
How long does it take?
A first release ships in 12 to 18 weeks. Three to four weeks of that is discovery and the contract audit, roughly eleven weeks is build, and the last three to four weeks are two parallel settlement cycles.
The schedule risk is the contract audit rather than engineering. Most hosts discover that signed terms, amendment letters and what finance actually applies have drifted apart over the years, and reconciling that is a commercial conversation on someone else's calendar.
Why can our retail ERP not do this?
Because it models the wrong transaction. Oracle Retail, Microsoft Dynamics 365 Commerce and Aptos are built around goods you buy and resell, with a supplier and a cost price. A concession is the inverse: you never owned the stock, you sold someone else's and retained a share.
They can be made to represent that with departments and journals, and plenty of hosts do exactly that. The tell is whether the actual calculation has migrated into a workbook outside the system. If it has, the platform is holding the accounting and not the commercial model.
How much does the self billed invoice piece add?
Typically $15,000 to $25,000 within a first release. The cost is not the document, it is the properties the document must have: its own sequence, immutability once issued, correction only by credit note, correct tax treatment per partner including partners registered elsewhere, and a traceable path from the invoice back to the individual transactions that produced it.
Confirm the specific requirements in your jurisdiction with your tax advisers rather than with a developer. What the build must guarantee is that an issued document cannot be edited.
What does partner owned stock add?
It usually moves a project out of the first release band. Expect $50,000 to $110,000 for stock as a separate ownership class with receipts, inter store transfers, returns to the partner and counts, plus shrink calculated per partner per period and allocated by that partner's liability clause.
Defer it unless shrink is currently a live commercial dispute. If it is, it is often the fastest payback in the whole programme, because it turns an annual argument into a monthly number both sides can see.
Is a partner portal worth building?
Yes, but second. Partners value an accurate statement first, and a portal sitting on a calculation they do not trust multiplies queries rather than reducing them.
Once accuracy is proven, the portal earns its cost in two ways. Query volume drops sharply because partners can see the derivation themselves, and your concessions team stops pulling ad hoc weekly figures by hand. It also becomes a commercial asset, since brands notice which hosts are easy to trade with.
How do we handle a return processed at a different store months later?
As a dated adjustment linked to the original sale, computed under the contract terms that applied when the sale happened rather than today's terms, and landing in the current settlement period with a visible reference.
If your current process absorbs these into a departmental total, you have an unexplained variance every month and no way to answer a partner query about it. Ask any prospective developer to describe this case before you sign, because the answer separates people who have built settlement systems from people who have built reports.
Who owns the code?
You should own the repository, the cloud infrastructure accounts and the unrestricted right to hire another firm, in writing before kickoff.
It matters more than usual here because the system encodes the negotiated commercial terms with every brand on your floor. You should never need a third party's cooperation to change a rate, add a structure or produce evidence for a partner dispute.
Can custom software connect to the tools we already use, like QuickBooks, Stripe, and Google Workspace?
Yes, and connecting your existing tools is one of the main reasons to build custom: mainstream platforms like QuickBooks, Stripe, Shopify, and Google Workspace all publish documented APIs. Budget 1 to 3 weeks of work per integration depending on API quality and how much data flows in both directions. Ask any vendor whether they have integrated with your specific tools before, because quirks like QuickBooks' OAuth token handling and API rate limits get learned on someone's project, and it should not be yours.
Can I extend QuickBooks with custom features instead of replacing it?
Yes, and it is often the right first step. QuickBooks Online has a public API, so an agency can build a custom layer for quoting, inventory, or field service that pushes clean transactions into QuickBooks, which stays your ledger of record. Roughly half of the accounting engagements Digital Heroes scopes start this way because it costs a fraction of a full build and leaves your accountant's workflow untouched.
We run everything on spreadsheets and Airtable. How do we know it's time for custom software?
The reliable signals are re-typing the same data into multiple tools, one employee acting as human middleware between systems, and errors appearing in handoffs between teams. Hard limits force the issue too: Airtable's Team plan caps at 50,000 records per base, and Business costs $45 per seat per month, so a 20-person team pays about $10,800 a year for a tool it has already outgrown. When workarounds consume more hours than the tools save, the spreadsheet era is over.
Should the first version of my accounting software be an MVP?
Yes, but scope it around one complete workflow rather than a thin slice of everything. A strong first release fully owns, say, invoicing and receivables while QuickBooks keeps running the general ledger, letting you validate the software with real money movement in 10 to 14 weeks. In Digital Heroes projects, one-workflow MVPs reach a stable full system faster than big-bang replacements almost every time.
What should I prepare before contacting an agency about accounting software?
Bring three things: the 5 to 10 workflows that hurt most today, sample data such as your chart of accounts and a redacted month of transactions, and a list of every system the software must connect to, including banks and payroll. You do not need a formal spec; a good agency writes that with you during discovery. In our experience buyers who arrive with concrete workflow pain get accurate quotes, and buyers who arrive with a feature wishlist get padded ones.
What are the biggest mistakes first-time software buyers make?
Choosing the lowest bid, paying more than 30-40% upfront instead of on milestones, skipping a written specification, and having no maintenance plan for after launch. The most expensive of the four in Digital Heroes rescue projects is the missing spec: without written acceptance criteria, done becomes an argument instead of a checklist, and every disagreement resolves in the vendor's favor. Fix those four and you have avoided most of the ways these projects fail.
How do I calculate whether custom software will pay for itself?
Divide the build cost by the monthly benefit, where benefit is hours saved times loaded hourly cost, plus subscription fees replaced, plus any revenue the software unlocks. Three staff saving 10 hours a week each at a $40 loaded rate is about $62,000 a year, which pays back a $60,000 build in roughly 12 months. Across Digital Heroes internal-tool projects, 12 to 24 months is the normal payback range, and anything projecting under 6 months usually means the spreadsheet is hiding costs.
How much does custom accounting software cost for a small business?
Most small business accounting builds land between $25,000 and $75,000 for a working first version, while a full double-entry platform with invoicing, payroll, and reporting runs $100,000 to $250,000. Across 2,000+ projects at Digital Heroes, the biggest cost driver is how many external systems the software must connect to, not the accounting logic itself. A tool that automates a single painful workflow, like reconciliation or job costing, can come in under $20,000.
How long does it take to build custom accounting software?
A focused first version takes 10 to 16 weeks, and a complete QuickBooks-class replacement takes 6 to 9 months. In Digital Heroes delivery data, schedules slip most often during data migration and bank feed integration, so we budget those two phases at double the first estimate. Treat any promise of a full accounting system in under two months as a warning sign.
Who can build a custom accounting software system?
Digital Heroes builds custom accounting software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other accounting software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
