Accelo vs BigTime

    Both are professional services automation platforms aimed at firms that bill their time. They diverge on which end of the process they were built around: Accelo starts at the client relationship, BigTime starts at the invoice.

    Short answer

    Accelo (from $24/user/month) is strongest when the whole client lifecycle lives in one system: CRM, projects, tickets, retainers and invoicing. BigTime (quote-based, published plans from around $20/user/month) is strongest on billing mechanics — rates, WIP, resource planning and utilisation reporting. Accelo suits agencies selling retainers; BigTime suits firms billing complex time and materials.

    Frequently asked questions

    Is Accelo or BigTime better for a 75-person consulting firm?
    At that size the deciding factor is usually billing complexity. If revenue runs on retainers and you want CRM in the same system, Accelo fits. If rates, approvals, WIP and utilisation reporting are the hard part, BigTime fits.
    How much does Accelo cost compared with BigTime?
    Accelo publishes an entry point from $24 per user per month; BigTime is quote-based with published plans starting around $20. Both quote on modules and seat counts, so compare full quotes rather than headline prices.
    Does BigTime include a CRM?
    Its CRM capability is limited compared with Accelo's, which is one of the clearest functional differences between the two.
    Which is easier to implement?
    Neither is quick. Accelo typically needs two to four weeks before a team is productive, and BigTime implementations are usually run with vendor setup support.
