Hire on the data model. If a firm draws a products table with a quantity column, end the meeting. Expect $60,000 to $130,000 for a first release covering item-level reservation, contracts, an append-only consignor ledger, assisted intake and two channels, and $150,000 to $400,000 for six channels, payouts and tax reporting. Budget three to five weeks for opening balances.
Hiring a developer for a resale business is like taking on a buyer who has never touched a rack. They can explain what sells in theory, they interview well, and you learn what they actually understand the first Saturday one dress sells twice. Every other retailer sells the same item two hundred times. You sell one Patagonia fleece, once, and owe a stranger a share of it within thirty days, and the software has to tell a register scan from a marketplace checkout in the same second.
This category is hard to buy because the shape is deceptive. Ask five firms and most will price it as an ecommerce build with a commission report attached, because that is the nearest thing they have shipped. The actual product is a ledger of other people's money wearing price tags: fourteen thousand rows each with a quantity of one, an owner who is not you, a markdown clock, an expiration that transfers ownership, and a payout obligation with tax consequences. The failure mode is not a bug report. It is a consignor who does not believe your number, which is a relationship problem you cannot patch.
What a consignment software development company actually does
The visible build is a point of sale (POS) screen, a consignor portal and a set of statements. That is the easy third. The rest decides whether the system survives its first busy quarter.
It starts with the item as the source of truth, carrying a state machine: available, reserved, sold, returned, expired. A register scan fires a reservation event rather than decrementing a count, and channel workers race to delist everywhere within seconds, with each failure surfaced to a human rather than found through a refund. That decision is most of what you are paying for.
Alongside it sits an append-only financial event log. Sold at $120, channel fee, split applied under contract version two signed on a stated date, consignor credit, return reversal. The balance is derived and never stored as fact, so a correction in April cannot silently rewrite February and a statement can be reproduced for any past date. Then the contract itself becomes a versioned object attached to the item, so splits can slide by price band, markdown schedules can differ by category and consignor tier, and the nightly repricing job writes a reason code on every change.
Around that, the pieces that only exist here. Expiration notices with delivery receipts stored against the item, because ownership transfer is the legal event and you may need to prove notice went out on the right date. Assisted intake, where a photo station and a vision model draft brand, category, material, measurements and a channel-appropriate title so the tagger reviews rather than types. Payout rails with retries. W-9 collection at onboarding with year-to-date totals per tax identity. Dormant balances ageing into a due diligence queue.
What it really costs in 2026
These are Digital Heroes delivery bands. The biggest driver is the number of sales channels, because each one without a public API needs a maintained browser integration that keeps costing money after launch.
| Project tier | Cost | Timeline |
|---|---|---|
| Item-level reservation and consignor ledger layered on your existing point of sale | $35,000 to $70,000 | 8 to 10 weeks |
| First release: item model, versioned contracts, append-only ledger, assisted intake, consignor portal, two marketplaces plus your web store | $60,000 to $130,000 | 12 to 16 weeks |
| Full platform: six channels, ACH payouts with failure handling, tax reporting, dormancy queue, multi-location routing, buy-outright with dealer reporting | $150,000 to $400,000 | 6 to 12 months |
| Opening balance reconciliation from your current system | Priced separately | 3 to 5 weeks |
Two line items are missing from most quotes and both will hurt. The first is that opening balance reconciliation. Your export from a packaged consignment tool will carry duplicate consignors, three spellings of the same person, items with no intake date and balances that do not reconcile. Rebuilding an honest, signed-off opening balance per consignor is the difference between launching and launching into a dispute season, and no import script does it for you.
The second is ongoing integration maintenance. Channels without public APIs change their pages, and a browser-driven integration is a small permanent commitment rather than a one-time deliverable. Ask for it as a monthly figure per channel. A firm that promises six clean API integrations including the ones that do not offer public APIs has not shipped this and is pricing a project they will discover in month four.
Signals of a strong partner
- They draw item, consignor, versioned contract and an append-only event log. Without being prompted, and before price comes up.
- They explain the oversell problem back to you. Reservation events, idempotency, and specifically what happens when a delist call fails at 2:14pm on a Saturday.
- They tell you which channels have real APIs. And which need a maintained browser integration, with the maintenance priced monthly rather than waved away.
- They propose a reconciliation plan, not an import. With a signed-off opening balance per consignor and a named owner on your side.
- They raise tax identity and dormancy first. W-9 collection at onboarding, year-to-date rollups per tax identity across locations, and dormant balances ageing into a queue rather than zeroed.
- They put assisted intake in the first release. Intake speed is your growth ceiling, and drafting the record from photographs is where the hours actually come back.
Red flags
- A products table with a quantity column. That is a general retail model and it cannot express one-of-a-kind inventory reserved across six places at once.
- A stored balance field. If the consignor balance is a number the system writes rather than derives, a correction will quietly rewrite history and your defence in a dispute becomes a manager's memory.
- Six clean API integrations promised. Some resale channels do not offer that, and a firm claiming otherwise is describing a project it has not done.
- Compliance only comes up because you raised it. Tax identity rollups and unclaimed property dormancy are structural rather than a later module, and a firm that never mentions them bolts them on badly.
- The payments account in their name. The payments provider account, the cloud accounts and the repository belong to your company from week one, not at handover.
Questions to ask on the first call
- Whiteboard the data model. Where does a single item live, and where does the money it generated live?
- A dress is scanned at the Northside register at 2:10pm and a buyer checks out on a marketplace at 2:14pm. Walk me through both paths second by second.
- Which of our six channels have public APIs, which need a maintained browser integration, and what does that maintenance cost per channel per month?
- A consignor disputes her March statement. Show me what your system produces and how long it takes.
- Our contract steps markdowns by category and transfers ownership at day ninety. How is the notice sent, and how do you prove it was sent on the right date?
- What exactly happens to our current export, and what does a signed-off opening balance per consignor involve?
- How are W-9s collected, and how do year-to-date payouts roll up per tax identity across three locations?
- Who owns the repository, the cloud accounts and the payments provider account, and from which commit?
A simple way to decide
Skip the proposal comparison and buy a paid discovery phase from your two strongest candidates. Two to three weeks each on a fixed fee, and the deliverable is a written specification you own: the item and ledger model, the reservation and delist design including failure handling, the contract and markdown rules as they appear in your agreements, the channel list marked by integration type with maintenance costs, the payout and tax design, the reconciliation plan for opening balances, and a phased build priced by phase. You keep the document whichever firm you pick.
Then go live in one store before touching the others, and run the old system alongside for one payout cycle. Digital Heroes works product requirements document first and contracts through India LLP, US LLC and UK LTD entities, so the agreement and the intellectual property assignment sit under law your own advisers read. The client holds the repository, the cloud accounts and the payments provider account from the first commit.

Frequently asked questions
How much does it cost to hire a consignment software development company?
Item-level reservation and a consignor ledger layered on your existing point of sale run $35,000 to $70,000. A first release with versioned contracts, an append-only ledger, assisted intake, a consignor portal and two marketplaces runs $60,000 to $130,000 over 12 to 16 weeks. Six channels with ACH payouts, tax reporting, dormancy handling and multi-location routing run $150,000 to $400,000 across 6 to 12 months.
What is the fastest way to tell if a developer understands consignment?
Ask them to whiteboard the data model before price comes up. The right answer separates the item, the consignor, a versioned contract and an append-only financial event log, and it comes out without prompting. If they draw a products table with a quantity column, they are pricing an ecommerce build, and their system will not be able to reserve one dress across six sales channels in the same second.
Why does migration cost so much on these projects?
Because your export will carry duplicate consignor records, several spellings of the same person, items with no intake date and balances that do not reconcile, and none of that survives an import script. Rebuilding an honest opening balance per consignor typically takes three to five weeks with someone from your side signing it off. Insist on it, because launching with a ledger your consignors do not believe ends the project in month one.
Should marketplace integrations be priced as one-off work?
Only the ones with real public APIs. The resale channels that do not offer one need a browser-driven integration that breaks whenever the site changes, so it is a small permanent commitment rather than a deliverable. Ask for the maintenance cost per channel per month in writing. A firm promising six clean API integrations including channels that have none has not built this before.
Do we own the code and the payments account?
You should own the repository, the cloud accounts and the payments provider account in your company's name from week one, not handed over at the end. At Digital Heroes the client owns the code from the first commit. Ownership covers the data model and the marketplace integrations, not just the front end, and a developer wanting to host in their own organisation is proposing a lock-in you will pay for at every renewal.
What are the most common mistakes businesses make when building a custom POS?
The top three Digital Heroes sees: treating offline mode as a later feature when it must shape the architecture from day one, rebuilding payment processing instead of integrating a certified provider, and copying every Square feature instead of the 15 workflows staff actually use. A fourth is skipping real hardware testing, since receipt printers and barcode scanners fail in ways emulators never show. Each of these is cheap to avoid in week one and expensive to fix in month six.
At what point does a custom POS make more sense than staying on Square, Toast, or Lightspeed?
The crossover usually arrives when your combined subscription and processing costs pass roughly $30,000 to $40,000 a year, or when a workflow you depend on simply does not exist off the shelf. A 10-location restaurant on Toast's published $69 per month plan, plus device fees, add-on modules, and processing markup, often clears that bar; a single cafe on Square's free plan or a boutique on Lightspeed Retail at $89 per month almost never does. Custom also wins when the POS is your product, for example if you plan to license it to other operators.
How many SaaS seats do we need before building custom becomes cheaper?
The crossover usually shows up between 20 and 50 seats on premium tiers. Salesforce Enterprise lists at $165 per user per month, so 40 users cost about $79,000 a year in subscriptions, which is real money against a custom system you would own outright. Run the comparison over three years: if subscription spend beats the build cost plus 15-20% annual maintenance, custom wins on price before you even count workflow fit.
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.
What should I have ready before I contact an agency about building a POS?
Bring three things: a written list of your 10 to 15 must-have workflows (returns, split payments, voids, shift close), your last three months of processing statements, and every system the POS must talk to, such as QuickBooks, your loyalty program, or a kitchen display. Agencies quote against unknowns, and this preparation tightens estimates by 20 to 30 percent in Digital Heroes scoping calls. You do not need wireframes or a technical spec; producing those is the agency's job.
What tech stack should a custom POS be built on?
Choose the stack around one requirement: the register keeps selling when the internet drops. That points to a local-first client, commonly Flutter or React Native on tablets or Electron on desktop registers, with an embedded SQLite database and background sync to a cloud backend in Node.js or Python on PostgreSQL. Payment SDKs narrow the choice further, so confirm your processor, for example Stripe Terminal, officially supports your target platform before committing.
Who owns the code when an agency builds my software?
You should, completely, through a written intellectual property assignment that transfers everything on final payment; without that clause, copyright stays with whoever wrote the code by default. Insist that the repository lives in your own GitHub organization from day one and that hosting, domains, and third-party accounts are registered to you. Also check for licenses to the agency's proprietary frameworks buried in the contract, because those can make switching vendors practically impossible even when you own your own code.
Why do agencies charge for a discovery phase instead of quoting for free?
Because an accurate quote requires real work: mapping your workflows, finding the edge cases, and writing a specification, which typically takes 1 to 3 weeks and costs $2,000 to $10,000 at Digital Heroes depending on system complexity. You leave discovery owning a written spec and a fixed price you can take to any vendor, so the money is not locked into one agency. Free estimates are guesses, and the guess usually becomes your budget overrun six months later.
What happens to a custom POS when the internet goes down?
A properly built POS keeps ringing sales offline: orders, catalog, and pricing live in a local database on the register, and completed transactions queue and sync once the connection returns. Card payments are the real constraint; certain certified terminals support store-and-forward offline card acceptance with a per-transaction risk limit you set, and cash always works. Confirm your agency designs offline-first from day one, because bolting it on later means rewriting the data layer.
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.
How do I vet a development agency for a POS project specifically?
Ask to see a live POS or payments product they built, then ask exactly how they handled offline mode, receipt printing, and PCI scope, because those three areas expose anyone who has only built ordinary web apps. A competent agency will name the payment SDKs they used, such as Stripe Terminal or Adyen, and describe their terminal certification process without checking notes. If the portfolio is all marketing sites and dashboards, keep looking.
How much should a small business budget for its first custom app or website?
For a focused first build, most small businesses land between $8,000 and $60,000: roughly $8,000 to $45,000 for a custom website and $25,000 to $60,000 for an internal tool or simple web app, based on Digital Heroes delivery across 2,000+ projects. Customer-facing products with payments, logins, or a mobile app start around $40,000. Quotes far below these bands usually mean a template with your logo on it, not software shaped around your workflow.
How many developers does it take to build a POS system?
A typical Digital Heroes POS team is 4 to 6 people: one backend developer, one or two client developers for the register app, a designer through the first half, a QA engineer, and a project lead. That size delivers a single-location system in about 3 to 4 months. Be skeptical of anyone pitching a one-developer POS build, because payments, offline sync, and hardware testing each demand dedicated attention.
Who can build a custom POS software system?
Digital Heroes builds custom POS 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 POS 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.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it. The YouTube channel is at https://youtube.com/@DigitalMarketingHeroes, the Fiverr profile at https://www.fiverr.com/shreyanshsin261, and the Upwork profile at https://www.upwork.com/freelancers/shreyanshsingh. Client reviews sit on Clutch at https://clutch.co/profile/digital-heroes-0 and Trustpilot at https://www.trustpilot.com/review/digitalheroes.co.in, and the company page is at https://www.linkedin.com/company/digital-heroes-1/.
Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
