How much does custom POS software cost?

Real builds commonly start around $80,000 and reach $250,000 plus with certified payment hardware integrations and multi-location back office, per 2026 development cost guides, before the 15% to 25% annual operating budget industry guides recommend.

Why would anyone build when Square is free?

Almost nobody should. The build case appears at multi-location volume where negotiated interchange-plus processing beats published flat rates by meaningful dollars, in verticals the platforms serve poorly, or when the POS is itself the product being sold.

Can a custom POS still use Square or Clover hardware?

Generally no; certified hardware pairs with its platform. Custom builds integrate their own certified terminal stacks, which is a meaningful share of the budget and timeline, and exactly the kind of scope a discovery phase must price before anyone commits.

Has Batch Group built POS systems?

Yes. Batch Group Software Development builds custom point-of-sale and vertical ERP systems for merchants and enterprise clients, alongside the payments infrastructure its divisions run on. [TODO: confirm with Tristan] which client POS builds can be referenced publicly.

What a Custom POS System Costs and When It Beats Square

The short answer

A custom POS build commonly starts around $80,000 and climbs with hardware integrations and certifications, against off-the-shelf systems like Square that publish free software and 2.6% plus 10 cents processing. Building wins only with unusual workflows, many locations, or when owning the platform and its processing economics is the business itself.

What Does Each Path Cost?

The comparison starts lopsided on purpose: off-the-shelf POS is exceptionally good in 2026.

	Off-the-shelf (Square-class)	Custom POS
Software	Free entry plans; published paid plans by vertical	$80,000 to $250,000 plus to build, per 2026 development cost guides
Processing	Published 2.6% plus 10 cents in person	Negotiated interchange plus at volume; you choose the processor
Hardware	Bought or financed, works day one	Certified terminal integrations are their own project
Time to live	Today	Six to twelve months
Upgrades	Continuous, free	Your roadmap, your budget
Best fit	Nearly everyone	Platforms, franchises, unusual verticals

Where Can a Build Actually Win on Money?

The processing line is where custom sometimes pays. A 12-location group doing $500,000 a month on a published 2.6% flat rate pays about $13,000 monthly in processing. On negotiated interchange plus at that volume, with wholesale interchange averaging near the high 1s per Visa and Mastercard's published tables plus a thin markup, the same volume can clear closer to $10,500.

That $2,500 monthly spread, $30,000 a year, will not fund a $150,000 build quickly on its own. Add per-location software savings against published per-location plan pricing, workflow fit, and ownership of the roadmap, and the five-year math can work for multi-location groups. For a single location it essentially never does, which is why the honest first recommendation at one or three locations is a Square, Clover, or Toast plan matched to the operation.

When Is Off-the-Shelf Simply the Answer?

Single locations, standard service models, and anyone who needs to open next month should not consider building. The published economics are unbeatable at small scale: free-to-cheap software, hardware that works out of the box, and processing at known published rates. The mature platforms also carry the compliance load, PCI scope, terminal certifications, offline modes, that a custom build must fund explicitly. The custom conversation starts seriously at franchise scale, at unusual verticals the platforms serve badly, or when the POS is the product you intend to sell to others, which is a software business decision, not a restaurant equipment decision.

What Does a Custom POS Project Actually Involve?

The build is more than screens, and pricing it means naming the parts.

Order and catalog engine modeled on the vertical's real workflow
Certified payment integration: terminal certification timelines are a project of their own
Offline resilience: the register must sell through an internet outage
Back office: reporting, inventory, users, multi-location roll-ups
Compliance scope: PCI obligations shift depending on integration architecture
The year-two budget: published guides put ongoing cost at 15% to 25% of the build annually
