Contact us
Email support@gridinvoices.com for support, refunds, privacy requests or security concerns.
For a purchase-related request, reply to your Gumroad receipt email to contact the seller. You can also use the creator contact option for the purchase in your Gumroad library. Gumroad's contact instructions explain this route.
Response commitment
Altamira Systems responds to support email within 24 hours of receipt. This means an initial human response, not guaranteed resolution within 24 hours. A complex issue, Google outage, payment-provider review or account recovery may take longer; we will explain the next step.
What we help with
Assisted pilot setup covers Google authorization, business details, a sample invoice and PDF check, and a backup recovery check. Email support covers installation, activation, using the purchased app, refunds, privacy requests and troubleshooting. Optional update renewal is not required to ask about an existing purchase or submit a security report.
Custom development, bookkeeping, tax advice, third-party account recovery and recovery of every damaged or deleted record are not included promises. If a request needs additional work or a separate charge, we will describe it and seek agreement before proceeding.
What to include
- Your purchase email or verified installation account, app version and a short description of the problem.
- The steps that led to it and a redacted screenshot, if useful.
- For payment issues, a receipt/order reference. For a privacy request, the information you want to access, correct, export or delete.
Never send passwords, authentication tokens, full license keys, payment-card details or unredacted client records. Do not publicly post a security issue containing sensitive details. We will arrange a specific, consented support exchange if access to a file is needed.
