OhmFlow is invoicing and payment collection software built specifically for solo electrical contractors, not adapted from generic field-service software.

Most invoicing tools are either too simple (a basic invoice generator with no context for the trade) or too complex (built for shops with dispatchers, crews, and enterprise budgets). OhmFlow sits in between: powerful enough for real electrical work, simple enough to use standing in a customer's driveway.

Core features:

AI-powered invoicing: type job notes or snap a photo, and OhmFlow turns them into a professional invoice in about 45 seconds, ready to send from your phone Room-by-room invoicing and PO fields, built from feedback from real electricians using the product on real jobs Payment collection and tracking via Stripe, with automatic past-due tracking so you're not manually chasing customers for payment Custom material pricing book that updates from supplier invoices or receipts, so estimates reflect real costs and you can see job profitability Photo receipt and supplier invoice parsing that updates your cost book or applies costs straight onto a job invoice QuickBooks sync for open invoices and payments, so your books stay clean without extra data entry Gmail OAuth email integration, so invoices go out from your own business email Works as a web app across phone, tablet, and desktop, no separate app store download required

Who it's for: Electricians at the inflection point of going independent. Recently formed an LLC, thin digital footprint, tired of chasing payment on paper invoices or juggling three tools to get a job billed and paid. If you're running one truck and don't have time for software built for a ten-person dispatch team, OhmFlow is built for exactly that.

Support: Founder-led onboarding and support. The person who built the product answers your questions directly, not a ticket queue.

Questions & Answers

As answered by people managing Joist and OhmFlow.

What makes your product unique?

OhmFlow's answer:

  • Built for one person, not scaled down from a team tool. Most invoicing software in this space is designed for shops with dispatchers, crews, and multiple techs, then feature-stripped or repriced for solo use as an afterthought. OhmFlow was built from the start for one guy running one truck.

  • AI invoicing that actually saves time in the field. Type job notes or snap a photo, and it becomes a ready-to-send invoice in about 45 seconds. No manually filling out line items on a form.

  • Founder-built from real conversations, not a feature checklist. It came out of talking to more than 70 electricians about what actually slows them down, not a generic product roadmap adapted from another trade.

  • Every feature came from an actual paying customer. Room-by-room invoicing, PO fields, and the material cost book all exist because a real electrician using the product asked for them.

  • Founder-led support, not a ticket queue. Questions and issues go straight to the person who built the product, not a support team working off a script.

  • Price locked for life for early customers. $97/month, guaranteed to stay at that price through future price increases and new features for the first founding members.

  • Material cost tracking tied directly to profitability. The pricing book updates from real supplier invoices and receipts, so a solo contractor can see what a job actually made, not just what was billed.

Why should a person choose your product over its competitors?

OhmFlow's answer:

  • It's built for exactly one kind of business, not adapted for it. Solo electrical contractors get software designed around how they actually work, not a scaled-down version of a tool built for shops with dispatchers and multiple techs.

  • Invoicing takes seconds, not minutes. Type job notes or snap a photo, and OhmFlow turns it into a ready-to-send invoice in about 45 seconds, right from the job site.

  • The price doesn't change on you. Founding members lock in $97/month for life, including through future price increases and new features, with a 30-day money-back guarantee.

  • Support comes from the person who built it. No ticket queue, no scripted responses. Questions go straight to the founder.

  • Every feature came from a real electrician, not a roadmap meeting. Room-by-room invoicing, PO fields, and the material cost book all exist because an actual paying customer asked for them.

  • It shows real job profitability, not just what got billed. The material pricing book updates from supplier invoices and receipts, so a contractor can see what a job actually made.

  • Getting paid doesn't require chasing anyone. Stripe payment collection and automatic past-due tracking are built into the app, not bolted on.

How would you describe the primary audience of your product?

OhmFlow's answer:

OhmFlow is built for solo electrical contractors, electricians running their own business without a crew or dispatcher. It's designed for someone who's out doing the work during the day and handling invoicing and payment collection on their own time, usually from a phone rather than a desk.

What's the story behind your product?

OhmFlow's answer:

  • OhmFlow started with conversations, not a spec sheet. Before building anything, I talked to more than 70 electricians about how they actually ran their invoicing and got paid. The same problems kept coming up: paper invoices, chasing payment, no easy way to see if a job actually made money.

  • The first version came together after one of those conversations turned into a live demo, then a same-day close. That customer became the first real user and shaped a lot of what the product does today, from room-by-room invoicing to how the material cost book works.

  • The goal was never to build another all-in-one platform. It was to build the smallest, fastest tool that actually fits how a one-truck electrician works day to day.

Which are the primary technologies used for building your product?

OhmFlow's answer:

  • React
  • Supabase
  • Vite
  • Gemini (AI-powered invoice parsing)
  • Stripe (payments)
  • QuickBooks integration
