Distributor Billing Reconciliation for MSPs is a startup idea for MSPs. MSPs pay through distributors (Pax8, NinjaOne); autopay silently breaks after an ACH switch with no reminders, causing penalties, or they get billed for 50 more devices than they manage. A thread in r/msp drew 51 upvotes and 46 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Spreadsheets and Gradient MSP, and that still leaves this job open. Hotness is 3.45, Warm. Strong pain. Clear willingness to pay. The thread drew 51 upvotes and 46 comments. Gaps in existing tools. A few weeks of work. A first version is a moderate amount of work, about 3–4 weeks, priced between $50 and $199 a month and charged as a B2B subscription. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Market size · estimate
How big this could get
A bottom-up estimate for Distributor Billing Reconciliation for MSPs: real customer counts × a realistic price. Not a forecast.
$33.6M a year
28,000 MSPs · 70% of US managed service providers (est.)
$13.2M a year
11,000 MSPs · MSP communities
$264K a year
220 MSPs · 2% of the reachable segment in three years
What that means
220 MSPs at $100/mo = $264K ARR
Medium confidenceHow we estimated this
- Base: 40,000 US managed service providers (est.).
- Has the problem: 70% (assume 70% resell licences through distributors).
- Revenue per MSP: $1,200 per year ($99/mo).
- Reachable: 40% (MSP communities).
- Three-year capture: 2% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.
Source: CompTIA counts 100,000+ US solution providers and MSPs; we assume 40% run managed services

Is this idea already taken?
People already use Spreadsheets, Gradient MSP. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Moderate. A tight MVP is about 4 weeks (3–4 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is MSPs. Charge a B2B subscription, and test a price between $50 and $199 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
