Hire on integration receipts, not on category claims. A firm that says it integrates with point of sale (POS) should name the export files it has parsed out of Passport and Commander. A focused first release across your whole fleet runs $60,000 to $130,000 in 12 to 16 weeks. Under about eight sites on one platform, keep your back office and spend the money on labor.
Hiring a developer for a convenience chain is like hiring a mechanic who has only ever worked on one make of car, then opening the hood on a fleet you assembled by acquisition. Nine sites on Passport, six on Commander, two on an old Ruby2, four tank gauges on a TLS-350 and the rest on something else, plus a jobber who emails bills of lading as phone photographs. Every one of those is a separate piece of work, and none of it shows up in a demo.
The category is hard to buy because the specification already exists and nobody recognizes it. It is your controller's spreadsheet, the one the whole company depends on and that finance rebuilt around because the back office could not answer the question. Vendors quote against a feature list instead, which is why the number in the proposal and the number at the end of the project are so often unrelated. The other complication is that your users are third shift clerks with high turnover, so anything that takes more than forty seconds at the counter will not get done, whatever the training deck says.
What a convenience store software company actually does
The screens are the easy half. The work is in the plumbing between systems that were never designed to speak.
Fuel is the largest dollar flow at the thinnest margin, and reconciling it means polling site controller movement and journal exports on a short cycle, reading tank gauge levels and delivery events directly, parsing the bill of lading for gross, net and temperature corrected gallons, then running a rolling variance per tank and alerting a person by text rather than waiting for a month end spreadsheet. Inside the store, the equivalent work is modeling a promotion as a real object with effective dates, participating items, expected retail and expected allowance per unit, pushing the price book down to every site and reading the movement file back to confirm it landed.
Then the parts that feel like administration and are not. Lottery tracked at pack and book level rather than as one department total, since a book of instants is bearer paper sitting in a bin on third shift. Paper invoices photographed at the counter while the vendor is still standing there, with extraction pulling every line and checking unit cost against the price book. And a shift close where the lottery number, the cash number and the register number have to agree before a manager can close.
What it really costs in 2026
These are Digital Heroes delivery bands from our own work rather than a market survey.
| Scope | Cost | Timeline |
|---|---|---|
| Pilot: one problem, five stores, a single point of sale platform | $30,000 to $55,000 | 6 to 8 weeks |
| Focused first release: one or two problem areas done properly across the whole fleet | $60,000 to $130,000 | 12 to 16 weeks |
| Full back office: fuel, price book, invoices, lottery, labor and accounting posting | $150,000 to $400,000 | 6 to 12 months |
| Support, price book rule changes and onboarding acquired sites | 15 to 20 percent of build per year | Retainer |
Two costs disappear from nearly every quote in this category.
The first is site controller remediation. Proposals assume the movement and journal exports are switched on and correct. On stores you acquired, they have often been misconfigured for years and nobody noticed because nobody was reading them. Fixing that is discovery, then a visit per site, and at some locations it requires the point of sale vendor's own technician at their rate on their schedule. Ask for it to be quoted as a per site line with an assumption stated, because it is the item most likely to move your go live date.
The second is rollout. Sixty stores is not six stores with a larger number, it is a training and support program on third shift, a cutover per site, and four to eight weeks of parallel running where both systems read the same exports and you reconcile store by store until they agree. Chains that cancel the incumbent contract at go live end up turning it back on. Time the cancellation to your renewal date, not your launch date, and put that gap in the budget as an overlap rather than a surprise.
Signals of a strong partner
- They can define wet stock variance without looking it up. If the vocabulary is not already theirs, you are funding their education.
- They name file types, not categories. Movement and journal exports from a specific site controller, a tank gauge polled over serial to network, a trading partner invoice feed from your wholesaler.
- They ask what happens when a site loses internet for six hours. It will, and the answer decides whether store staff can still close a shift.
- They design the counter interaction first. Anything a clerk has to do while a vendor waits has a forty second budget, and a partner who tests that on site understands the business.
- They keep the build outside cardholder data scope by design. Never touching the payment path is dramatically cheaper than building inside scope, and it should be a written boundary.
- They ship to real stores inside sixteen weeks. A firm wanting nine months before anything touches a counter has never trained a third shift cashier on anything.
- They give you the database as well as the code. Your price book, cost history and vendor master are the asset, and they should sit in accounts you control.
Red flags
- They quote a fixed price without an inventory of your platforms. A mixed fleet is the main cost driver, so a number produced before that list exists is fiction.
- Lottery treated as a department total. It signals they have never reconciled a state invoice against activated packs, and that is where physical shrink hides.
- Scan data described as generating a file. Producing the submission is the easy part. Checking what the manufacturer actually paid against what you expected is the part that pays for the project.
- Get your vendors onto electronic invoicing. Your bread and beer vendors will not, and a partner who says this has no plan for the paper that is actually in the drawer.
- No mention of the tank gauge or the fuel compliance record. Daily reconciliation with an auditable trail is a regulatory obligation, not a reporting preference.
Questions to ask on the first call
- Which site controller exports have you parsed, and from which point of sale platforms by name?
- How would you poll our tank gauges, and what changes if a site has an older model?
- How do you reconcile a delivery when the bill of lading arrives as a phone photograph from the jobber?
- How would you check what a tobacco manufacturer actually paid against the allowance we expected?
- How do you track instant lottery at pack level and match it to the state settlement file?
- What does a clerk do at the counter with a paper invoice, and how long does it take?
- How does this stay outside cardholder data scope, and will you put that boundary in the statement of work?
- What happens to a store that has been offline for six hours at shift close?
- When we acquire four stores on a platform we do not currently run, what does onboarding cost?
A simple way to decide
Buy a paid discovery phase before you buy a build, and make the deliverable a document rather than a decision. Two to three weeks, a small share of the project, ending with a written specification you own: the platform inventory per site with the export status of each, the tank gauge models, the trading partner feeds, the promotions and price book rules taken from your controller's spreadsheet, the compliance boundary, and a phased cost with the assumptions listed. Take that to every firm you are considering. The quotes become comparable for the first time.
Digital Heroes works this way as a matter of course, builds and runs its own retail products including HeroCheckout and ShopScore, and hands the client the repository from the first commit.

Frequently asked questions
How much does it cost to hire a convenience store software company?
A pilot covering one problem across five stores on a single platform runs $30,000 to $55,000. A focused first release doing one or two problem areas properly across the whole fleet runs $60,000 to $130,000 over 12 to 16 weeks. A full back office replacement covering fuel, price book, invoices, lottery, labor and accounting posting runs $150,000 to $400,000 phased across 6 to 12 months.
What does a mixed point of sale fleet do to the price?
It is the largest driver, ahead of store count. Each platform needs its own integration and its own testing, and acquired stores frequently have site controller exports that were misconfigured years ago and never read. Correcting those means discovery, a visit per site, and sometimes the point of sale vendor's technician at their rate. Get it quoted per site with the assumption written down.
How small is too small to justify a custom build?
Around eight sites on one fuel brand and one platform with no foodservice program. At that size a packaged back office will do the job and you will never recover the build cost. The signal that it is time is not that the tool is bad, it is that you have built a shadow system of spreadsheets and custom reports around the tool and are now paying for both.
Can a developer really read our paper vendor invoices?
Yes, and it is the most reliable use of extraction in this category. A clerk photographs the invoice at the counter while the vendor waits, and the system pulls vendor, invoice number, date and every line with item, quantity and unit cost, then checks each line against the price book and flags cost changes above a threshold you set. Exception review replaces keying.
Do we own the code and the price book data?
You should own the source, the database, the infrastructure accounts and the deployment pipeline from day one, with no ongoing license to the developer for software built for you. At Digital Heroes the client owns the code from the first commit. A firm that wants to retain ownership and rent the system back is a product company, and that is a different relationship with different economics.
How much does it cost to build a custom POS system for a small business?
A single-location custom POS covering checkout, inventory, receipts, and payment integration typically lands between $30,000 and $70,000, based on Digital Heroes delivery data across 2,000+ projects. Multi-location systems with kitchen displays, franchise reporting, or offline sync usually run $80,000 to $250,000. The biggest cost drivers are custom hardware support and how much of the payment flow you build versus integrate.
What does it cost to maintain a custom POS after it launches?
Budget 15 to 20 percent of the original build cost per year, so a $100,000 system runs $15,000 to $20,000 annually for hosting, OS and payment SDK updates, security patches, and small feature changes. Digital Heroes structures this as a monthly retainer for most POS clients, commonly $1,000 to $3,000 depending on location count. For multi-location operators that figure usually still undercuts the per-terminal subscription fees they were paying before.
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.
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.
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.
What happens to my software if the agency shuts down or we stop working together?
Nothing dramatic, if the engagement was set up correctly: the code sits in your repository, hosting runs on your cloud account, and a handover document explains how to deploy and operate the system. Any competent replacement team can then take over in days rather than months. If the agency controls the repo, the servers, or the domain, fix that now, because renegotiating access during a dispute is the most expensive place to discover the problem.
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.
Can I build my product on a no-code tool like Bubble instead of hiring developers?
For testing whether anyone wants the product, yes, and Bubble's paid plans start at $29 a month, which is the cheapest validation you will ever buy. The ceiling arrives with complex data relationships, heavy integrations, performance at a few thousand users, and the fact that you cannot export a Bubble app to servers you control. A path many Digital Heroes clients take: prove demand on no-code, then rebuild custom once revenue justifies it, treating the no-code version as a paid prototype rather than a foundation.
What should I prepare before contacting a software development agency?
A one-page brief beats a 40-page requirements document: the business problem in plain words, who will use the system, the 5 to 10 workflows it must handle, the tools it must connect to, and your budget range and deadline driver. You do not need wireframes, a specification, or technical vocabulary; producing those is the agency's job during discovery. Stating a budget range up front is the single best move, because it gets you honest scoping instead of a quote engineered to win the meeting.
How long does it take to develop a custom POS system?
Plan on 12 to 16 weeks for a working first version with checkout, catalog, payments, and reporting, and 6 to 9 months for a full multi-location rollout. In Digital Heroes projects the schedule risk is rarely the software, it is hardware certification and payment processor onboarding, which can add 3 to 6 weeks if started late. Kick off the merchant account and terminal applications in week one, not at the end.
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.
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.
