A self-storage facility has the strangest payment mix in small business: almost nobody pays at a counter. Rent arrives monthly from cards stored months or years ago, move-ins happen online at midnight, and the costliest payment event is not a sale at all — it is a failed recurring charge on a tenant who has stopped answering, attached to a unit the facility may soon have to lock. Pricing that mix with a retail rate card misses all three costs: the card-on-file rate on the rent roll, the processor choice hidden inside the facility software, and the failed-payment machinery that decides how much rent is recovered instead of written off.
This guide prices the mix on dated Canadian rates checked on 2026-10-18. Every rate is named with its source in the table. The worked example is an illustration built from published rates, not a quote — facilities should rerun it on their own unit count and average rent before negotiating anything.
Why self-storage payments cost differently: rent on file, not sales at a till
First, the dominant transaction is recurring and card-not-present. A stored card charged monthly prices as an online or card-on-file transaction, not as an in-person sale, even if the tenant first handed the card over at the office. The relevant comparison is therefore among online, recurring, and bank-debit rates — the in-person headline that leads most processor marketing is the rate a storage facility uses least.
Second, the software chooses the processor more often than the owner does. Facility management software integrates a short list of processors, and in Canada that list can be very short: Storable Easy's Canadian help documentation gives its customers two options, Moneris or Authorize.net, and specifies that the Authorize.net account must be an e-commerce, card-not-present account rather than a retail, card-present one. A facility that picks software first may have already picked its processing shortlist.
Third, failure is a recurring line item. Cards expire, are replaced, or decline; tenants fall behind. The processing question is not only the rate on successful rent but what the setup does on failure — reporting, retries, card updating, reminders, and access consequences — because a recovered $150 payment is worth more than a fraction of a percent saved on the payments that were never in trouble.
The rates on the table, checked 2026-10-18
| Option | Recurring / online rate | In-person (move-ins at the office) | Monthly fee |
|---|---|---|---|
| Stripe (online) | 2.9% + CA$0.30 domestic; dispute fee $15 | — in this comparison | None |
| Square (flat rate) | 2.8% + 30¢ online · 3.3% + 15¢ keyed | 2.5% per credit transaction · Interac debit 0.75% + 7¢ | None |
| Helcim (interchange-plus; published averages) | 2.31% + 25¢ average online | 1.79% + 8¢ average | None |
| Rotessa (PAD, for tenants on bank debit) | $25/mo + $0.50 per transaction (1–500 transactions) | — | $25, included in the rate shown |
| Facility-software processing (Storable Easy, Canada) | Processor-dependent: Moneris or Authorize.net are the two Canadian options named in its help documentation | Account must be e-commerce / card-not-present for Authorize.net | Software subscription is separate |
Two cautions. Helcim's online figure is a published average for interchange-plus pricing, so a facility's actual average moves with tenant card mix; its Tier 1 margin in the Canadian fee disclosure is interchange plus 0.50% and 25¢ for card-not-present and recurring transactions at monthly card volume up to $50,000. And software-integrated processing is priced by the underlying processor's account, not by the software's feature list — the table names the constraint, and the section below prices the standalone routes a facility can compare against it.
Worked math: one facility, 200 units, $150 average rent
The illustration: 200 occupied units at $150 average monthly rent — $30,000 a month collected in 200 recurring payments, all card-on-file or online. Processing only; facility software subscriptions and taxes are excluded.
Stripe: $30,000 × 2.9% = $870.00, plus 200 × $0.30 = $60.00. Month: $930.00.
Square online: $30,000 × 2.8% = $840.00, plus 200 × 30¢ = $60.00. Month: $900.00. If staff instead key stored-card numbers manually at Square's keyed rate — 3.3% plus 15¢ — the same month is $990.00 plus $30.00, or $1,020.00: how the charge is entered changes the bill.
Helcim at its published online average: $30,000 × 2.31% = $693.00, plus 200 × 25¢ = $50.00. Month: $743.00.
PAD via Rotessa, for comparison: $25.00 plus 200 × $0.50 = $100.00. Month: $125.00 — for tenants who will pay by bank debit instead of a stored card.
The spread: about $775 to $805 a month between the card routes and PAD on the full rent roll. No facility will move every tenant to bank debit, but the arithmetic prices the incentive: each long-term tenant who switches from a Stripe-priced card to PAD removes about $4.65 a month in card cost and replaces it with about $0.50, plus a share of the $25 monthly fee.
The card-route gap matters too. On this rent roll, the difference between the Helcim average and Stripe is about $187 a month, roughly $2,244 a year — enough to justify comparing a standalone interchange-plus account against the software's integrated option, where the facility's volume and the software's processor list allow both to be quoted on the same month.
Failed payments: the second processing bill
Storage billing software treats failure as a workflow, and the features on offer name the steps. Stora's payments page describes automatic retries for failed card payments, a card updater that refreshes expired or replaced cards, automated reminders that chase late payers, a tenant portal for updating payment details, and the ability to link billing with smart entry to block a late payer's access until rent is cleared. Storable Easy offers a Failed and Declined Payments report showing the date, customer, payment type, failure reason, and amount, with an optional failed-recurring-billing email to the tenant and the facility. These are vendor descriptions of their own features, not independent measurements — a facility should test them on its own delinquency list rather than buying a recovery percentage.
Policy is the other half, and a Canadian operator's published terms show the shape of it. Sentinel Storage's user agreement provides that if a cheque or pre-authorized debit payment is not honoured by the client's bank, an NSF fee of $35 applies and the operator may stop accepting cheques or PAD from that client; it also provides that possession of the unit is not granted until the first rental period's payment has been received. A facility's own agreement should state its returned-payment fee, its retry and notice sequence, and its access consequences with the same clarity — drafted for its province and its lease, not copied from another operator.
The cost logic is simple. A failed $150 charge retried successfully costs the normal processing fee. A failed charge that is never recovered costs the rent, the staff time spent chasing it, and eventually the unit's turnover. Spending a modest amount on card updating, reporting, and a documented retry sequence is not a software luxury in this sector; it is the difference between processing cost as a percentage problem and rent loss as a dollars problem.
Decision framework: pricing a facility account
- List the software's processor options first. If the facility software names two Canadian options, get both quoted; if a standalone account is possible, quote it on the same rent-roll month.
- Compare recurring rates, not counter rates. The rent roll is card-on-file volume. In-person pricing matters only for office move-ins and merchandise.
- Check how stored cards are charged. Keyed entry at 3.3% plus 15¢ versus an online charge at 2.8% plus 30¢ at Square is a $120-a-month difference on this illustration for identical rent.
- Offer PAD deliberately to long-term tenants. At about $0.50 a payment against roughly $4.35 to $4.65 of card cost per $150 unit, even a partial shift is material — with the agreement, notice, and returned-payment policy documented.
- Audit the failure workflow before signing: failed-payment reporting by reason, automatic retries, card updating, tenant self-service for new card details, and how access control responds to an unpaid unit.
A note on steps: this is a pricing and decision guide, not a how-to procedure, so the framework above is the actionable part rather than a numbered fix.

FAQ
Why is storage rent priced as an online payment when the tenant signed up in person?
Because the recurring charges are made to a stored card without the card present. The rates that govern the rent roll are the online, recurring, and card-on-file rates in the table — 2.31% plus 25¢ at Helcim's published average, 2.8% plus 30¢ at Square online, and 2.9% plus CA$0.30 at Stripe — not the lower in-person rates.
Can a Canadian facility choose any processor with its storage software?
Not always. Storable Easy's Canadian help documentation names two options — Moneris or Authorize.net — and requires the Authorize.net account to be an e-commerce, card-not-present account. Check the software's list before negotiating with a processor it cannot connect to.
Is PAD worth offering when most tenants prefer cards?
For long-term tenants, the arithmetic is strong: about $0.50 per payment through Rotessa against about $4.35 to $4.65 of card cost on a $150 unit at the published online rates. The facility keeps cards as the default and prices PAD as an option worth asking stable tenants about at renewal.
What should happen when a recurring payment fails?
A documented sequence: the failure is reported with its reason, the card is retried and, where the software supports it, updated automatically if it was replaced, the tenant is reminded and can update details in a portal, and the facility's own agreement governs fees and access consequences. One Canadian operator's published terms set a $35 fee for a dishonoured PAD or cheque — a facility needs its own stated policy, not silence.
