Free-plan allowances differ between the pricing page and billing documentation; confirm the included volume and chargeable-resolution definition before estimating cost. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
