Service businesses cannot answer a “service not provided” chargeback with shipping evidence. The core question is whether the promised service occurred. Build the case from calendar, attendance, work product, communications, and the agreed scope.

Identify the disputed unit of service

State exactly what the charge purchased: - one appointment; - monthly retainer for August; - design milestone; - event booking; - consulting package; - repair visit; - subscription access.

A $3,000 retainer can include several activities. Do not submit an annual contract and expect the issuer to infer that the disputed month was performed.

Prove scheduling and attendance

Useful records: - booking confirmation; - calendar invitation; - check-in record; - video meeting attendance; - signed work order; - technician GPS/dispatch record; - event attendance; - customer message sent during or after the session.

Calendar creation alone is weak because a scheduled meeting can be canceled. Pair it with evidence that the event occurred.

For remote services, meeting-platform logs can show join times. For field service, work-order signatures and photos can link the visit to the customer location.

Show the work product

Attach only the deliverables relevant to the charge: report, design file, repaired-equipment record, campaign launch, code commit, completed checklist, or other output.

For confidential or bulky deliverables, show enough metadata to prove completion without unnecessarily submitting sensitive content.

If the service involved advice rather than a tangible file, meeting notes, follow-up email, and customer acknowledgement can establish performance. For hosted software or membership access, define the paid service period and preserve the account entitlement/activation dates, outages, pauses, cancellation status, and support history. Login records can show use, but no login by itself does not prove access was unavailable; connect the account state to the contract and any reported interruption.

Address cancellation and rescheduling

If the customer canceled, determine whether the charge was a valid cancellation/no-show fee under terms accepted before the appointment.

Show: - booking terms; - cancellation cutoff; - customer cancellation timestamp; - scheduled service time; - any reschedule offered.

Do not reframe a cancellation-fee dispute as “service was provided” if no service occurred. The actual defense may be that an agreed cancellation fee was correctly charged, which can fall under a different dispute category or evidence requirement.

Retainers need allocation

For recurring professional services, keep a monthly activity summary. It can list calls, tasks, deliverables, hours if relevant, and customer approvals.

A generic invoice “August retainer — $2,000” does not show performance. Link the charge to the service record.

If a retainer is for availability rather than hourly work, preserve the contract language explaining what availability buys and evidence you remained available under those terms.

Write the chronology around completion

Example: - Jul 2: customer purchased four-session package; - Jul 9, 16, 23, 30: sessions held; - meeting logs show attendance; - Jul 30: final worksheet sent; - Aug 3: customer emailed “thanks for the sessions”; - Aug 20: dispute filed as service not provided.

The customer’s own acknowledgement can be especially strong when paired with system records.

Prevent the next case with routine completion records

Use signed work orders for field work, attendance logs for appointments, milestone approvals for projects, and monthly summaries for retainers.

Send completion emails that name what was delivered and invite the customer to report issues promptly. Those are good service practices even when no dispute ever occurs.

A service chargeback should be defendable from records created while providing the service, not from an employee reconstructing a month of work after the bank notice arrives.

Translate internal records and explain exceptions

A code such as “WO-884 closed” is not self-explanatory. State what was done, when and where, who received the result, which customer or account it concerns, and which charged appointment, milestone, or service period it covers. Preserve the source event ID and time zone for meeting, dispatch, or account logs. If a schedule or scope changed, include the customer’s dated request and the accepted replacement plan. Reconcile a cancellation, outage, or refund entry that appears to conflict with a completion record before submitting the packet.

When the customer missed or blocked service

If the customer did not attend, canceled late, failed to provide access, or did not supply materials, do not describe the service as completed. If the charge is an agreed no-show, cancellation, or mobilization fee, show the term accepted before booking, the reminder and appointment, the cancellation or access-failure time, and the calculation of the fee. The processor may classify that dispute differently from “service not provided”; use the exact claim and evidence instructions shown in the case. A policy alone does not establish that the customer accepted it or that the fee was lawful.

Corroborate performance with records tied to the customer

A meeting-platform attendance export, building check-in, customer-signed work order, or message requesting the next project phase can corroborate an internal completion flag. Keep the original record and identify its source and date. A GPS point can show a technician was near a site, but it does not by itself prove the contracted work was done. Tie independent logs to the accepted scope, deliverable, and any customer acknowledgement.
