Terms of Service

Last updated: August 5, 2026.

These terms govern a merchant's ("you," "merchant") use of Fillsy ("we," "us," "Fillsy") — a registered business in Ontario, Canada, providing a slot-recovery service for Square Appointments merchants. By connecting your Square account, you agree to these terms.

What we do

When one of your appointments cancels, we try to fill it — first by offering the customer who cancelled the same week's other open slots at full price, then by offering your existing clients a chance to move an upcoming booking earlier at full price, and finally by offering the slot at an escalating discount as it approaches, bounded by the floor and ceiling you control. The first person to claim it is rebooked automatically on your Square calendar.

Fees

Our current fee is 10% of the final sale price (after any discount), capped at $50 per filled slot — charged once per recovery chain, on net-new revenue only, when it closes. Because the fee is a percentage of what the customer actually pays after the discount, not the original list price, a shallower discount always means a larger fee for us — we're never incentivized to push you toward a deeper markdown than necessary. This fee is calculated on the final sale price alone. The rate and cap above are current terms, not a locked-in commitment — see Changes to these terms below for how we update them and notify you before a change takes effect:

• We never take a percentage of a tip. Every payment link we generate supports tipping by default, and 100% of any tip goes to your business/staff.
• We never take a percentage of tax.
• A move-up (a client moving their own upcoming booking earlier) is never fee-bearing — it relocates a sale you already had, it doesn't create one.

You only ever pay for a chair we actually filled. There is no monthly fee, no setup fee, and no contract term — see Termination below.

Trial

Eligible merchants currently get the first $500 of recovered revenue free, or 30 days, whichever comes first. These figures are current terms, not a locked-in commitment — see Changes to these terms below.

Early pilot merchants participate under a separate, individually signed pilot agreement in addition to these Terms of Service. That agreement is not published on this site and is provided directly to each pilot merchant. These Terms continue to apply to a pilot merchant's general use of Fillsy, but where the pilot agreement addresses something specifically (including its own fee, trial, or term provisions), the pilot agreement prevails.

Refunds, cancellations, and no-shows

Discounted slots booked through Fillsy are final sale. If a client cancels a recovered booking they paid for, no refund is issued — the same way a last-minute discounted fare or a flash-sale ticket typically works. This is what makes the discount a genuine incentive to claim fast, not a reservation with no consequence to backing out of. If a recovered booking is cancelled with enough notice left before the slot, the SLOT itself goes back through the same recovery process as any other cancellation — but the original payment stands.

If a payment collected through Fillsy is refunded, our fee on that transaction is reversed in the same proportion as the refund, never both charged and kept on a refunded sale. That applies whether you issue the refund yourself, at your own discretion through your Square Dashboard, or Fillsy issues one on the basis below.

Where the business cancels a booking a client already paid for, Fillsy may refund that client. Any such refund is funded from your own Square balance, exactly as a refund you issued yourself would be. This is a goodwill measure and not an entitlement: nothing here obliges Fillsy to issue a refund, guarantees one will be issued in any particular case, or makes Fillsy responsible for funding one your balance cannot cover.

No-shows on a recovered booking are yours to keep. Every slot we fill is prepaid — if the client doesn't show, you've still been paid for the appointment, and our fee doesn't change either way.

No guarantee of results

Fillsy is a tool, not a guarantee. We do not promise a specific fill rate, a specific dollar amount recovered, or that any particular slot will be filled. The Revenue Opportunity Report and any projections we show you are estimates based on your own booking history, not commitments. Nothing on this site or in the Service is professional, financial, legal, or business advice — you're responsible for your own decisions about pricing, staffing, and how you run your business.

Your responsibilities

You're responsible for the accuracy of your Square catalog, pricing, and booking policies, and for configuring the guardrails available to you (discount floor/ceiling, volume caps, eligible services, pause) to match how you want your business represented. You're responsible for maintaining your own compliance obligations as a merchant independent of this service.

Your data

Your data stays yours. Your booking records, catalog, pricing, and client information belong to you. Connecting your Square account does not transfer ownership of any of it to us, and nothing here gives us the right to sell it or to share it with another business for their marketing.

You grant us permission to use that data for two things, and no others.

To run the service for you. Detecting cancellations, choosing who may lawfully be offered a slot, sending that offer, rebooking, taking payment where a discount applies, and producing your reports and dashboard. This is the only purpose for which we ever use information that identifies one of your clients.

To improve the service and build new ones, using aggregated or de-identified data only. Individual clients are never identified or identifiable in this, and our Privacy Policy sets out in plain terms what it covers, including the benchmark figures shown to other businesses. Tell us at the contact below if you would rather your account was excluded, and it will be, with no change to the service you receive.

This permission lasts while your account is connected and, for aggregated and de-identified data already produced, afterward. Disconnecting stops any further use of your identifiable data beyond what we are required to retain, which the Privacy Policy describes.

Termination

Either party may terminate at any time. You can disconnect Fillsy from your Square Dashboard whenever you like — there is no minimum term and no cancellation fee. On disconnect, we stop sending offers and cancel anything scheduled immediately; see our Privacy Policy for what we retain afterward and for how long.

Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE, OR THAT ANY DEFECT WILL BE CORRECTED. See "No guarantee of results" above for what this means specifically for the revenue and fill-rate figures we show you.

Third-party services

The Service depends on Square, our SMS delivery provider, and other services we don't own or control. We're not responsible for their outages, errors, policy changes, or acts or omissions — including a missed cancellation, a failed booking, or an SMS that doesn't send or arrives late — even where those affect your use of the Service.

Fillsy is an independent service and is not affiliated with, endorsed by, or sponsored by Block, Inc. or Square. "Square" is a trademark of Block, Inc., used here only to describe compatibility with their platform.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (A) WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE, EVEN IF WE'VE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES; AND (B) OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (I) THE FEES YOU PAID US IN THE THREE MONTHS BEFORE THE CLAIM AROSE, OR (II) CAD $100. Some jurisdictions don't allow certain limitations on liability, so some of the above may not apply to you.

Indemnification

You agree to indemnify and hold us harmless from any claim, damage, liability, or expense (including reasonable legal fees) arising from: your use of the Service; the accuracy of your Square catalog, pricing, or booking data; your compliance obligations as a merchant, including obtaining and maintaining any consent required to message your clients; or your violation of these terms or of any law.

Governing law

These terms are governed by the laws of the Province of Ontario and the federal laws of Canada applicable in Ontario, without regard to conflict-of-laws principles.

Changes to these terms

If these terms change materially — including the fee rate, fee cap, or trial amounts above — we'll update the date above and notify merchants directly before the change takes effect.
