Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Knowify

  • Additional users cost $29/month per person across all plans
  • Monthly billing costs 50% more than annual billing

Siteline

  • It serves subcontractors only, so a general contractor evaluating it is looking at the wrong side of the transaction entirely.
  • It does not do job costing, project management or payroll, so it is an addition to your systems rather than a consolidation of them.
  • Value depends on a clean integration to your construction accounting system, and contractors with heavily customised or elderly installations should confirm the connection before signing.
  • General contractor portals and billing formats change without warning, and although the vendor absorbs that maintenance you still feel it as occasional friction in a month-end window with no slack.
  • The billing team has to adopt it fully in the first month-end or they revert to spreadsheets under deadline pressure, which makes the implementation timing more delicate than the software suggests.
