The stack problem

Most businesses run on three or four apps that don't agree.

A register for the counter. Accounting software for the books. A payroll service. A spreadsheet or a separate system for rentals, vehicles or special orders. Each keeps its own copy of your customers, products and money — and someone spends every week keying numbers from one into the next.

  • Your register
  • Your accounting software
  • Check payroll
  • Your rental software
  • Dealer inventory spreadsheets
  • Your job board
  • The spreadsheets in between

Mobius

One login, one customer list, one set of books.

  • POS
  • Inventory
  • Invoicing
  • Accounting
  • Payroll
  • Work boards
  • Vehicles
  • Rentals

Mobius replaces the stack with one system. Ring a sale, and the books are already done.

Built for businesses running three or more systems today. Mobius pays by printed check (no direct deposit or tax filing) and doesn't do dealer finance (F&I), so keep those tools if you rely on them. If you only need a card reader and a simple register, a lighter tool will cost you less.

One set of books

Everything posts to one ledger, the moment it happens.

A contractor pays for a special order.

The deposit is held, the PO goes to the supplier, the stock is received, the invoice is issued and the deposit is applied.

A rental car comes back a day late.

The extra day is priced across the whole rental, the security deposit is refunded, a damage charge is billed and the tax is recorded.

Your money and your records, handled carefully.

Card numbers never touch Mobius.

Online and terminal card payments run through Stripe. If you use your bank's terminal, Mobius records only the last 4 digits and the approval number.

Export your data.

Export your reports to CSV (most also to Excel or PDF), plus your customer, product, order and ledger lists, while you're subscribed — including right before you leave.

Roles and two-factor sign-in.

Nine built-in roles on every plan; custom roles on Business. Two-factor sign-in (authenticator app or emailed code) for back-office accounts, and an admin can require it.

Change history.

Edit history on invoices, checks, journal entries and settings. Undo on every void.

Encrypted in transit.

Every connection uses HTTPS.

Questions

What is Mobius?

One business system: point of sale, inventory, invoicing, double-entry accounting, payroll, work boards, and vehicle sales and rentals, all sharing one set of books.

Who is it for?

Small and medium retail stores, hardware stores and vehicle dealerships — especially businesses running three or more separate systems today.

How much is it?

Starter is $79/month and Business $175/month, with unlimited users on both. Apps such as Payroll and Work Board are priced per business, and Enterprise starts at $600/month. See pricing for the details.

Can I try it?

Yes. Each business gets one free trial: 30 days, no card needed. If you don't add a card, you aren't charged — the subscription ends with the trial and the account pauses until you subscribe, so export anything you need first.

Does it work without internet?

The Windows app keeps ringing cash sales for up to 24 hours offline by default (you can set 0 to 168 hours). Card readers, house charges, discounts, exchanges and rentals wait until you're back online.

Is there a Mac app?

Not right now. Mobius runs in any modern browser on a Mac. The desktop app, with offline selling and direct printer support, is Windows only.
