Write to hello@sumoffice.com — the shared address for every request below. The team that builds SumDoc and SumSheet answers — within one business day.

The supplier of SumDoc and SumSheet is HEALTH INFORMATIC SECURITY SYSTEM, S.L. (Málaga, Spain). Company details and trademarks are on the legal information page; personal data processing is in the privacy policy. Files you send for a check or a pilot are used only to run them through the engine, are not passed to third parties, and are deleted on your request to the same address.

Request a pilot

A pilot is not a presentation but a check on your documents: you open your file inside your application, edit it, save it and reopen it. What exactly is checked and how long it takes is described on the Pilot and acceptance page.

To get straight to business, it helps to state up front:

• which product you need — SumDoc (DOCX documents), SumSheet (XLSX spreadsheets) or both;
• what your application is built on — desktop, web or server-side processing;
• which operating systems must be supported;
• what the user must be able to do inside the document;
• whether there are perimeter restrictions: an air-gapped network, data storage requirements;
• volume — how many documents and how many installations;
• timeline — when you want to start the pilot.

Attach a representative document without confidential data — this is the fastest way to start. We run it through the engine and reply with what opens, what saves without loss, and what will need further work — before any commitments.

The cost depends on which application embeds the engine and how it is delivered. Describe that — and within one business day you will get a written proposal; no call is needed for this.

Beta program

The SumDoc and SumSheet builds are openly available — installing SumDoc and installing SumSheet — no request is needed for that. If you are ready to try builds before the general release and send your remarks, leave a request — the form on the next page, three fields. An email with beta in the subject works too — an email with the subject filled in. Participation is free. In return we ask for feedback: what did not open, what opened incorrectly, what was missing.

What participation gives:

• early access to SumDoc and SumSheet builds before the public release;
• a say in priorities — feedback from beta participants is taken up before anything else;
• a direct channel to the team without the general support queue.

What is expected from a participant: open your real documents in a new build from time to time and report discrepancies. No formal obligations or contract are required.

Technical question

If you are already reading the reference and something specific does not add up — a command, an operation, a field, behavior on error — write to the same address and include:

• which product, build version and operating system;
• what you called and what you expected to get;
• what you got instead, including the full error text. For spreadsheets that is the operation name and the code from the response; documents have no code — include the error line and the command name, and if an edit is involved, also result.mutation.result_kind: it arrives even when the envelope is successful;
• one full request line and one full response line;
• the smallest anonymized file that shows the problem;
• whether it reproduces in a new process.

Before writing, it is worth looking at the troubleshooting pages — for SumDoc and for SumSheet: some cases are already covered there, along with what exactly to check.

An error in the documentation

Found an inaccuracy, a cut-off sentence or a link to nowhere on this site? Write to the same address with documentation in the subject — email with a ready subject — and give the page address. It helps more than it seems.
