How the alternatives charge
We describe the pricing model rather than reprinting prices. A copied price goes stale without warning; a pricing model does not.
Avalara AvaTax
Priced by transaction volume and by number of filing jurisdictions.
Since Wayfair, states can require registration once a remote seller crosses a revenue or transaction threshold in that state. Thresholds differ per state.
Most states source an intrastate sale to the buyer address; a minority source to the seller address. The wrong rule produces the wrong rate on every invoice.
Where a marketplace collects sales tax on your behalf, that revenue must be reported but excluded from your own remittance.

Does Missouri change which sales-tax software I should pick?+
Partly. Missouri levies a 4.225% state rate, with combined state and local rates of 4.225% – 11.988%. Intrastate sales are sourced to the seller address, so the rate follows your location. The national sales tax rules are the same wherever you are registered, so the software shortlist barely moves — what moves is the configuration. Anything you choose has to handle sales tax 4.225% – 11.988% · origin sourcing correctly on every invoice without you remembering to set it per transaction.

How much does HelloBooks cost in Missouri?+
Pricing is national, not regional: $15 and $39 per month, billed annually, in USD, plus a free tier. Prices are in USD. Sales tax on the subscription is applied where your state requires it. Prices are per organisation with unlimited users, so a business in Missouri pays the same as one anywhere else in the United States.
What do most businesses in Missouri use today?+
In practice the shortlist here is usually QuickBooks Online, Xero, Wave — those are the products with the most local install base and the most CPAs who already know them. That familiarity is a genuine cost saving, and it is the main reason to stay put if nothing else is broken.
Will my CPA be able to work in HelloBooks?+
Yes, and at no extra cost. Advisors get their own login with their own permissions, and the seat is free — so bringing in a Missouri-based CPA does not change your bill. That matters most where the advisor relationship, not the software, is the real switching cost.
