In their own words
Avalara AvaTax
Avalara AvaTax calculates tax in real time for sales and purchasing workflows. It covers sales tax, consumer use tax, VAT, communications tax, occupancy and lodging tax, and excise tax, and supports automated return filing and tax registration. Address validation uses geospatial technology to match transactions to tax regions rather than relying on ZIP codes. AvaTax connects with ecommerce, ERP, accounting, sales, and purchasing systems, and its REST API supports calculation, document modification, and address validation. Product taxability codes, AI-assisted item classification, custom rules, exemption certificate management, and jurisdiction-specific tax research support tax decisions. Reporting includes dashboards, natural-language search, and audit-ready trails. The service is available through web and API, with integrations including Shopify, NetSuite, QuickBooks, SAP, and Salesforce. Core Compliance costs $79 per month; Core Compliance + SST Services costs $69 per month for qualifying sellers. Qualified sellers may receive state-funded services in up to 25 states. Pricing also varies by plan and transaction volume.
Taxmo
Taxmo is UK bookkeeping and tax software for sole traders, freelancers, contractors, expats and small businesses. It tracks income and expenses and updates estimates for Income Tax, National Insurance and VAT as entries are added. Paid plans can submit VAT returns to HMRC through the Making Tax Digital API. Taxmo prepares and reviews Self Assessment returns but does not submit them to HMRC; MTD for Income Tax submission is marked as coming soon. Receipt capture extracts supplier, amount, date and VAT from photos and PDFs. Bank imports use read-only, on-demand Open Banking authorization, while CSV statement uploads have no history limit. The accountant platform syncs in both directions with Xero, QuickBooks and FreeAgent, and deadlines can be exported as an iCal feed. Taxmo offers web, iOS and Android apps plus API access; Pro subscribers get a read-only REST API limited to 300 requests per 15-minute window. There is a free plan and a free trial; paid plans start at £9.99/mo, excluding VAT.
