Sell Spreadsheet & Excel Formula Fixes From Your Bio

Sell spreadsheet formula fixes as a priced custom request linked from your bio: the follower pays upfront, submits the broken Excel or Google Sheets file plus a description of what is failing, and you return a corrected file inside a turnaround you set in advance. No calendar scheduling, no marketplace bidding. Custom Work lets you offer clearly scoped commissions and services: you set the price, the scope and the delivery time, and followers submit a brief and pay before you start.

No monthly fee, you only pay a small platform fee when you get paid. 8% platform fee when a follower pays for work, 5% platform fee on tips and goals. Card processing is separate.

The message usually reads something like "my VLOOKUP keeps returning #N/A" or "this formula worked yesterday and now the whole sheet is red." Answering it well takes real skill — spreadsheet errors are neither rare nor trivial. The European Spreadsheet Risks Interest Group (EuSpRIG) reports that "the majority (>90%) of spreadsheets contain errors," and that "about 50% of spreadsheet models used operationally in large businesses have material defects" (EuSpRIG research and best practice). A creator who can reliably diagnose and repair that class of problem is doing priced work, not a favor.

On your Brillay page, a follower picks an offer and pays upfront by card as a guest before you start, and you reply or deliver later (how Brillay works).

Should a formula fix be a quick question or a full service?

If the follower can describe the whole problem in a sentence — the cell, the error, what should happen instead — Paid Questions are the better fit.

Brillay's Paid Questions let a follower pay your set price to ask you one private question, and you send back one written reply, privately. Brillay's Custom Work page explains that when a follower submits a brief, they can attach up to five files (the broken workbook, a screenshot of the error, a sample of the correct output), so the creator has everything needed before starting. Our sibling page on answering Excel formula questions for pay covers the one-question, one-written-reply version of this offer in more depth. The same file-first structure suits other technical repair work too — see running a paid service for fixing a broken Webflow site for a comparable example outside spreadsheets.

How do I scope a "fix my broken formula" service?

Scope the service around one file, one stated problem, and the delivery time you set, so the follower knows exactly what the fixed price covers. An open-ended "I'll fix whatever's wrong with your spreadsheet" listing invites scope creep and unpriced extra work. Brillay lets you set a delivery window of up to 5 days.

Set a delivery time from one hour to five days, based on how long a typical formula fix takes you. Set the listing's input, size limit, and deliverable inside that ceiling.

Naming a size limit matters because the underlying tools are enormous. Microsoft Support specifies a maximum Excel worksheet size of 1,048,576 rows by 16,384 columns, which is why "one tab" is a far more useful scope line than "one file" (Microsoft Support, Excel specifications and limits). Google Drive Help specifies that spreadsheets created in or converted to Google Sheets hold up to 10 million cells or 18,278 columns, so a shared Sheets link can be just as unbounded as a desktop workbook (Google Drive Help, files you can store in Google Drive).

If a sent file turns out to need a full rebuild rather than a targeted fix, you can decline the custom request as out of scope.

Use clear illustrative prices, such as $25 for one broken formula or $50 for several formulas on one tab, then raise the fixed price when the work takes longer or requires a rebuild.

What should the follower send before I start?

Ask for the actual file, the exact cell or formula that is failing, and what the sheet is supposed to do, so you are not reverse-engineering intent from a screenshot. In practice, missing context is a common reason a fix runs longer than the price accounted for; Brillay publishes no measured figure for that, so treat it as working guidance.

A short intake checklist keeps requests inside scope:

• The file itself (an Excel workbook or a shared Google Sheets link), not just a screenshot of the broken cell.
• The exact error — the cell reference, the error code (#REF!, #N/A, #VALUE!), or a description of the wrong output.
• The intended result — what the formula is supposed to calculate or return when it works.
• Anything already tried — knowing what the follower ruled out avoids re-testing a fix that already failed.
• A size or scope boundary — for example, "one tab only," so a 40-tab workbook does not arrive under a single-fix listing.

With Custom Work, you can return the corrected workbook once with a written note, up to five files, and/or links.

Why does this kind of fix matter enough to charge for it?

Fixing a broken formula is worth charging for because faulty spreadsheet logic has caused documented, multi-million-dollar losses at organizations with far more review resources than a free DM reply gets. A careful diagnosis and repair is a risk-reduction service, and the public case record gives a creator concrete language for pricing it.

Researcher Raymond Panko puts the average measured spreadsheet cell error rate at 3.9% across the human-error studies he reviewed (Panko, "What We Don't Know About Spreadsheet Errors Today," EuSpRIG 2015, arXiv:1602.02601).

"Based on human error research, we would expect spreadsheet cell error rates to [be] in the range of 1% to 5%.. The average across these studies is a cell error rate of 3.9%." — Raymond Panko, "What We Don't Know About Spreadsheet Errors Today," presented at the EuSpRIG 2015 Conference (full paper)

A 3.9% per-cell rate sounds small until it compounds across hundreds of linked formulas. Canadian power company TransAlta took a $24 million charge after a bidding error traced to a single cut-and-paste mistake in an Excel spreadsheet, according to the case records compiled by EuSpRIG:

"It was literally a cut-and-paste error in an Excel spreadsheet that we did not detect." — Steve Snyder, TransAlta CEO, as documented in case records compiled by EuSpRIG

Larger institutions have hit the same wall. The US Senate Permanent Subcommittee on Investigations announced in March 2013 that its 300-page bipartisan case history covered JPMorgan Chase credit derivative trades that "lost at least $6.2 billion last year" (US Senate Permanent Subcommittee on Investigations, "JPMorgan Chase Whale Trades," March 14, 2013). EuSpRIG's case record for that episode quotes JPMorgan's own Task Force Report on the arithmetic underneath it: "the spreadsheet divided by their sum instead of their average, as the modeler had intended".

Framing a formula-fix service around catching exactly those failures — a broken reference, a mismatched range, a copy-paste that shifted a cell — helps a follower understand what they are paying to avoid.

How is fixing a formula different from building a new template?

Fixing a formula means repairing logic inside a file the follower already has; building a template means creating a new workbook from scratch to a spec the follower hands over. Keeping repair and build as two separate listings prevents a "fix this" request from quietly turning into an unpriced full build at the lower price.

If a follower's ask is closer to "I don't have a tracker yet, can you build me one," that request belongs to a different offer, covered by our sibling page on selling a custom Excel template. Some creators run both listings side by side — a lower-priced fix tier for existing files, and a higher-priced build tier for new templates — so each request lands in the tier matching the actual work.

What else can I sell alongside spreadsheet fixes?

One Brillay link can hold your Custom Work, Paid Questions, Tips, Goals, and Brand Collaboration Inquiries; paid offers are one-time purchases rather than memberships, and creators can receive payouts in 41 countries. Each offer catches a different request without blurring the fix listing's scope.

• Tips: a way for someone who used a creator's free spreadsheet advice to say thanks without buying a specific fix.
• Goals: funding toward a stated goal, such as building a free public template library, shown with a progress bar rather than a shipped product.
• Brand Collaboration Inquiries: a separate inbox for spreadsheet-tool companies or finance-software brands that want to discuss a partnership.

Keep the formula-fix listing itself narrow — document repair, not open-ended spreadsheet consulting — so followers know exactly what they are purchasing.

How do I get a formula-fix service live?

List the service with a clear input (one file), a clear deliverable (a corrected file plus notes), and a delivery time you can consistently hit, then publish it as a custom request on your Brillay page. Brillay's own homepage FAQ states there is no follower minimum and nothing to apply for, so no approval step gates publication.

That is a meaningfully different starting position from a freelance marketplace. Fiverr's own Payment Terms of Service state that a seller's completed order "credits your account with Earnings equal to 80% of the purchase amount," a 20% commission on every order (Fiverr Payment Terms of Service). Brillay's fee structure is published on its pricing page (Brillay pricing). Here the commission lives on your own page at your own price, with the brief collected at checkout and the work paid for before you start.

Our guide on setting delivery times for services walks through picking a delivery time window inside Brillay's 5-day cap, rather than promising same-hour fixes that create pressure on every order. Once the listing is live, a follower pays upfront, attaches the file, and you send back the corrected workbook in one delivery — no separate invoice or freelance-marketplace profile needed.

Frequently asked questions

Four points shape a formula-fix service on Brillay: Paid Questions are one typed question and one written reply, while Custom Work lets followers attach files; you can decline an out-of-scope request; you set a delivery time of up to five days; and Brillay has no monthly fee, with the platform fee set out in the pricing answer below.

Can a follower send a file through a Paid Question instead?

No. Custom Work accepts attached files from the follower when they order.

What if the file turns out to need a full rebuild, not a quick fix?

Followers pay upfront; you can decline a request. A scope line such as "one tab, one stated error" makes that boundary easy to point to.

How long can I take to deliver a fixed file?

You choose how long you need to deliver the fixed file, from one hour to five days. Choose a window based on a typical week, not a fastest-possible delivery time.

What does Brillay charge to run this service?

The platform fee for this kind of order is set out near the top of this page. Card processing runs separately through Stripe, and those rates vary by country, currency, and card, so check Stripe's current pricing for your location (Stripe pricing).

Do I need a freelance-marketplace profile to offer this?

No. Brillay's homepage FAQ explains that there is no follower minimum and nothing to apply for, so it works from your first paying follower. Publishing a custom request requires no bidding, portfolio review, or marketplace approval step.

Create your free Brillay page and turn the next "can you fix this formula?" message into a priced custom request instead of a free favor.
