Here's the short version
A lower card-processing rate does not automatically make a POS switch cheaper. Hardware, software billing and migration costs determine when the savings actually reach your bank account.
For a hypothetical retailer taking $30,000 in card-present sales across 750 transactions each month, the existing terminal costs $982.50 per month. Square Free with a $899 Register costs $892.50 per month under the published standard rate used here, saving $90 monthly. Hardware-only payback is 9.99 operating months.
Two additional quotes illustrate how monthly and annual software fees change the result. They are calculation assumptions, not verified current Clover or Lightspeed offers. A cheaper monthly quote can pay back sooner, while an annual prepayment can create a temporary positive balance that disappears at renewal.

The store and the comparison rules
This is a modeled single-location gift shop, not a reported customer case. It uses one register, sells in store and has a $40 average card ticket. The existing paid-off terminal charges an assumed 2.9% plus 15¢ per transaction with no software fee.
The baseline is $30,000 × 0.029 + 750 × $0.15 = $982.50. Its effective rate is 3.275%. Keep monthly volume, transaction count and payment channel identical when comparing quotes.
Use two ledgers
Monthly operating cost = volume × percentage rate + transaction count × transaction fee + monthly software allocation. Monthly savings = old operating cost − new operating cost.
Simple payback = incremental hardware and one-time switching costs ÷ positive monthly savings. This formula applies to the monthly-billed model here, with software starting at go-live. Do not add the first software payment to the numerator and also subtract it in the same period's operating savings.
Cash ledger = avoided old costs − actual new processing payments − actual subscription payments − hardware and other switching payments. Put annual subscriptions on their payment dates. An allocated monthly expense is not another cash payment.
Base figures exclude taxes, shipping, accessories, termination fees, pre-launch subscriptions, financing, downtime and labor. Add actual amounts before making a purchasing decision. Billing and savings start at go-live in this model. It uses 52 ÷ 12 weeks per month and unrounded values until final display.
Weeks 0–1: Audit your current statements
Collect three months of statements. Divide total comparable fees by total card volume, including recurring processor charges. Separate hardware loan payments and one-time charges so you can see which costs actually disappear after switching.
Read the termination and equipment terms. A paid-off terminal may still have a processing commitment. A low effective rate alone does not settle the decision: inventory errors, staff time, reliability and required features can also justify a switch.
Weeks 2–3: Compare written quotes and workflows
Use the same product list and checkout tasks in each demo: sale, void, refund, inventory adjustment and end-of-day reconciliation. Ask whether trial hardware, payment processing and data migration are included; do not assume all three providers offer a completely free trial.
Confirm offline-payment eligibility and limits before testing a live transaction. Ask who bears the loss if a payment accepted offline later declines. Also confirm refund fees, settlement timing and support hours.
Square's official US pricing page lists Free at $0 monthly and its standard in-person rate at 2.6% plus 15¢. Square Register is listed at $899 before taxes and fees. These are the verified inputs for option A; custom or existing-account terms may differ.
Use Clover's official retail pricing page and Lightspeed's official retail pricing page to request comparable US quotes. Clover's displayed Retail Standard bundle uses Station Duo, so the original draft's Flex-only hardware cost cannot establish that bundle's acquisition price. Confirm Lightspeed's country, product series, annual payment schedule and compatible equipment.
Week 4: Separate equipment from subscription payments
| Option | Hardware | Software assumption | In-person rate | Cash at go-live, before processing |
|---|---|---|---|---|
| A. Square Register + Free | $899 | $0/month | 2.6% + 15¢ | $899 |
| B. Illustrative monthly quote | $749 | $84.95/month | 2.3% + 10¢ | $833.95 if month one is paid in advance |
| C. Illustrative annual quote | $248; assumes an existing compatible tablet | $1,068 prepaid every 12 months ($89/month allocation) | 2.6% + 10¢ | $1,316 |
Options B and C preserve the original draft's numbers solely to demonstrate the calculations. Their hardware, fees and compatibility must be replaced by a written quote. They are not equivalent hardware bundles or a brand ranking. Buying a lower-priced compatible Square device would also change option A's payback.
Weeks 5–6: Budget the migration
Clean up the catalog, export a backup and schedule training before a quieter trading period. A planning allowance of 10 owner hours is a scenario input, not a measured industry average.
Do not invent a flat $50 overlap charge. For the same routed sales and transaction count, extra processing cost equals the old fees minus the new fees on those payments; add actual duplicate software or terminal charges separately. Under this example, routing one quarter of one week's sales through the old terminal would add about $5.19 versus option A, before other overlap costs.
At $25 per hour, 10 owner hours add $250 to an economic-cost comparison. Keeping that separate from cash payback makes the tradeoff visible without pretending the owner's time has no value.
Week 7 onward: Calculate operating savings
| Setup | Percentage fees | Transaction fees | Software allocation | Total/month | Monthly savings |
|---|---|---|---|---|---|
| Old terminal | $870 | $112.50 | $0 | $982.50 | — |
| A. Square | $780 | $112.50 | $0 | $892.50 | $90 |
| B. Monthly quote | $690 | $75 | $84.95 | $849.95 | $132.55 |
| C. Annual quote | $780 | $75 | $89 | $944 | $38.50 |
Option B's simple hardware payback is $749 ÷ $132.55 = 5.65 operating months. Option A's is $899 ÷ $90 = 9.99 operating months. With go-live at the start of calendar week 7, these are approximately the 31st and 50th calendar weeks, respectively. The monthly model allocates costs evenly; actual billing dates can shift cash payback.
Annual prepayment changes the cash timeline
Option C saves $127.50 per month in processing before software. It pays $248 + $1,068 at go-live, then another $1,068 at each 12-month renewal. During the first year its cash balance is $127.50 × operating months − $1,316.
That balance first crosses zero after 10.32 operating months. At month 12 it is +$214 immediately before renewal and −$854 immediately after renewal. It crosses zero again after 18.70 months, but the month-24 renewal takes it back to −$392. It reaches zero again after 27.07 months and, under unchanged assumptions, remains positive through later renewals. This sustained cash payback is different from the first temporary crossing.
| Operating time | A. Square | B. Monthly quote | C. Annual quote |
|---|---|---|---|
| 0 months | −$899.00 | −$833.95 | −$1,316.00 |
| 3 months | −$629.00 | −$351.35 | −$933.50 |
| 6 months | −$359.00 | +$46.30 | −$551.00 |
| 10 months | +$1.00 | +$576.50 | −$41.00 |
| 11 months | +$91.00 | +$709.05 | +$86.50 |
| 12 months | +$181.00 | +$841.60 | −$854.00 |
| 18 months | +$721.00 | +$1,636.90 | −$89.00 |
| 24 months | +$1,261.00 | +$2,432.20 | −$392.00 |
At 12 months, the operating-cost comparison after hardware is +$181 for A, +$841.60 for B and +$214 for C. The cash table shows C at −$854 because the second year's subscription has just been paid. Do not call both figures first-year cash profit. The original three-year cash-payback claim double-counted the prepaid annual software.
What changes the result?
Transaction count and ticket size. The difference between options A and B is 0.003 × volume + $0.05 × transactions − $84.95. At a fixed 750 transactions, their monthly costs match at about $15,816.67 in volume. If the average ticket instead stays fixed at $40, transactions equal volume ÷ 40, and the crossover is about $19,988.24. These are different scenarios.
A smaller store. At $20,000 and a fixed 750 transactions, B saves $72.55 monthly versus the old terminal. Its $749 hardware payback becomes 10.32 operating months, around calendar week 51 with the same launch schedule. Do not carry over a calculation based on a fixed $40 ticket.
Other payment channels. Calculate keyed-in, online and invoice payments using each provider's actual channel rates. A universal 3.5% rate across all providers is not supported by this model.
Negotiation and support. This store processes $360,000 annually; Square's pricing page invites merchants above $250,000 per year to discuss custom pricing. Its Free plan lists weekday phone support for the first 90 days, while Plus is $49 monthly per location. Include the applicable plan's processing rate as well as the subscription when recalculating.
Choose on cost and operational fit
Start with Square Free if its included tools meet the shop's requirements and monthly subscription flexibility matters. Evaluate a Clover quote if the specific compatible bundle, workflow and processing agreement meet those requirements at an acceptable total cost. Evaluate Lightspeed if the quoted inventory and reporting features solve a measurable operating problem worth the additional cost.
Use the same checks for all three: required functionality, total acquisition cost, monthly savings, contract exit terms, support and migration risk. There is no defensible brand winner from unverified or mismatched bundles.
Next step: calculate your three-month baseline, then request itemized quotes with the same volume and transaction count. Build a dated 24-month cash ledger before signing, especially if software or hardware is prepaid.
FAQ
How do I calculate POS switching break-even?
Subtract the new monthly processing and software cost from the old monthly cost. For a monthly plan with no prepayment, divide incremental hardware and other one-time costs by positive monthly savings. For an annual prepaid plan, use a dated cash-flow ledger that includes renewals.
Is Clover cheaper than Square for this retailer?
The illustrative monthly quote costs $42.55 less per month than Square Free at $30,000 in card sales and 750 transactions. That does not establish that a current Clover package is cheaper: its compatible hardware, software, processing agreement and total acquisition cost need a written quote.
Does annual billing delay payback?
It can delay cash payback even when the allocated monthly cost is competitive. In the illustrative annual quote, cash first becomes positive after 10.32 operating months but turns negative again when the next annual payment is made at month 12. It becomes positive again after 18.70 months, turns negative at the month-24 renewal, and reaches sustained positive cash after 27.07 months under unchanged assumptions.
What migration costs belong in the budget?
Include termination fees, hardware tax and shipping, required accessories, paid setup, pre-launch software, actual overlap fees, financing costs and downtime. Track owner and staff hours separately or assign an explicit hourly value. There is no universal $50 migration fee.
