EPOS installation and setup costs: budget for the changeover
A delivered box is not a working system. Price the preparation, connections and checks needed to open for trading with confidence.
The short answer
EPOS setup costs can include a site survey, installation, configuration, data preparation, migration, integrations, training and launch support. Ask for a written scope showing who does each task, what counts as completion and which changes cost extra. Include your own team’s time and any service overlap.

Ask what “installation included” actually covers
Installation might mean remote guidance, equipment assembly, an engineer visit or a complete changeover. Those are different services. Request a task list for each site and device, including cabling or network changes, hardware configuration and payment activation.
Record who supplies and checks stock files, menus, customer records and opening balances. Confirm what happens to historical reports, gift cards, loyalty balances and outstanding deposits. An import is not complete until someone checks that the result is usable.
Build a setup schedule with named owners
| Workstream | Scope to confirm |
|---|---|
| Survey and installation | Site readiness, equipment placement, mounting, power, network access and travel. |
| Configuration | Tax settings, products, modifiers, permissions, receipts and reporting structure. |
| Migration | Source export, cleaning, test import, final import and exceptions. |
| Integrations | Accounting, ecommerce, bookings, ERP or CRM connections and subscriptions. |
| Testing | Sale, refund, failed payment, end-of-day report, payout and stock update. |
| Launch and handover | Training, changeover cover, escalation, documentation and acceptance criteria. |
Some services may be included or unnecessary. Mark them as included, separately priced or not required. Avoid paying for the same import or training task through both the main supplier and an integration partner.
Worked example: quote cost and internal effort
Fictional implementation. A survey costs £150, installation £350, configuration £200, migration £300 and an integration setup £250. Temporary overlap costs £120 and launch cover £200.
The external setup budget is £1,570. The business also expects 12 hours of data preparation at an internal £20 per hour: £240 of staff-time value. The combined resource budget is £1,810.
If those hours are worked within existing paid time, they are not automatically an extra £240 cash payment. Show additional overtime or cover separately. Do not also add the same overlap to a switching-cost entry elsewhere.
Resolve the difficult data before launch
Request a sample export before committing. Identify duplicates, missing fields and mismatched product codes, then agree how exceptions will be handled. Decide which history must migrate and which can be retained in a usable archive.
Lightspeed’s Retail onboarding guidance is one example of a shared process: it calls for prepared data and participation by the account owner or relevant key users. A supplier-led project still requires input and decisions from the business.
Use appropriate access controls for customer and business data. Ask the supplier for its approved migration process instead of moving sensitive records through an informal channel.
Make the handover measurable
Before signing off, run a sample sale, refund, split or partial payment where supported, and your ordinary closing process. Check that the receipt, stock movement, order destination and accounting records agree. Include a realistic busy-period workflow.
Set the cutover date, the person authorised to approve it and a rollback decision point. Confirm how refunds or disputes on the old system will be handled after the new one starts. Keep the previous service available for the agreed overlap only.
Get a priced process for scope changes. Extra locations, late data changes or custom reports can otherwise turn an apparently fixed setup quote into an open-ended project.
Carry implementation into the cost comparison
Put future supplier setup charges into the one-off budget. Keep staff time, recurring connector subscriptions and ongoing support in their own categories. For a staged rollout, record when each cost and licence begins.
Use the integration guide for connected software and the training guide for staff readiness. Bring the agreed scope alongside your calculator report when asking for a review.
Common questions
Does free installation mean no changeover costs?
No. Data preparation, staff time, network work, integrations and service overlap may sit outside the included scope. Ask for a written list of exclusions.
Should every historical record move into the new EPOS?
Not necessarily. Establish what the business needs in the live system and how required older records will remain accessible. Confirm the available export and migration options before leaving the old service.
