A Complete App Stack Under $100 a Month (With the Math)

"Keep the stack under $100 a month" is common advice that almost nobody prices out. So we did, using the verified entry prices of the apps in our kit — the published starting price of each, checked this week. The result: a genuinely complete stack — reviews, email, helpdesk, landing pages, and analytics — for $60.20 a month, with room to spare.

This is provisioning math, not a wishlist. Here is the build, the running total, the swaps, and — just as useful — the apps that cannot fit inside $100 no matter how you arrange them.

The $60.20 build

Five jobs covered, $39.80 of headroom left. Notes on each pick:

Judge.me at $15 flat. The paid Awesome tier is one price, not a contact ladder — the rare line item that will not creep. (And if $15 needs to become $0, the free plan's unlimited review requests will carry a small store; see the free-tier roundup.)

Omnisend at $11.20. The cheapest paid entry among the email platforms we track, with the prebuilt welcome, abandoned-cart, and post-purchase automations that do the actual work. Priced by contacts, so it grows as the list does — at entry, $11.20.

Gorgias at $10. Priced by ticket volume rather than agent seats, which is exactly the right shape for a small store: cheap while tickets are few, scaling only as support load does. Order data beside every ticket is the feature users most consistently praise.

PageFly at $24. Slot-based pricing — you pay for published page slots. One good landing page for your main traffic angle is the job here; the stock theme handles the rest of the catalog.

Triple Whale at $0. The free Founders Dash tier is a real dashboard, not a teaser, and at this stage analytics is a job a free tier covers honestly. Paid tiers price by store volume — a later decision, made when ad spend justifies attribution.

The swaps

The build is modular. The honest alternatives at each slot, with the new total:

• Klaviyo instead of Omnisend (+$8.80 → $69.00/mo). Klaviyo's $20 entry buys the category heavyweight and the deepest segmentation runway. If you expect to scale email hard, this is the better long buy.
• Loox instead of Judge.me (−$0.01 → $60.19/mo). $14.99 versus $15 is a wash on price; the real question is photo-first versus text-first proof. Note Loox has no free fallback tier.
• Kit instead of Omnisend (+$21.80 → $82.00/mo). Only if you are a creator-led store; at $33 its paid entry is the priciest of the three email platforms, though its free tier (to 10,000 subscribers) means many creator stores pay $0 here for a long time.
• Drop PageFly until needed (−$24 → $36.20/mo). If no page is carrying paid traffic yet, the builder can wait — or run its free plan for the first slot.

Maximum-swap version (Klaviyo + Loox + Kit is nonsensical together, but the priciest coherent build — Klaviyo, Loox, Gorgias, PageFly, Triple Whale free) lands at $68.99/mo. Still $31 under the line.

What busts the budget

Three apps in our kit cannot join a sub-$100 stack, and pretending otherwise is how budgets die:

• SE Ranking at $129/mo is over the whole budget by itself. That is not an indictment — it is a full SEO platform, priced for stores funding organic as a real channel. Until then, Google Search Console is free and covers the basics.
• Recharge at $99/mo + 1.49% + 19¢ per transaction consumes $99 of a $100 budget before its transaction fees start. It belongs in a stack when recurring volume pays for it — the math lives in our subscription apps guide.
• Spocket ($39.99) or Zendrop ($49) fit inside $100 only by displacing other jobs — the $60.20 build plus Spocket is $100.19, a whisker over the line; plus Zendrop it is $109.20. Dropshipping stores should run this same exercise with the sourcing app as the anchor line item and trim elsewhere (the helpdesk and review slots matter more than the page builder there).

The principle under the math

Notice what the $60.20 build assumes: free tiers where a free tier honestly covers the job (analytics), cheap flat pricing where it exists (reviews, helpdesk), and paid entries only for the jobs that directly touch revenue (email, landing pages). The budget is not the point — the underwriting habit is. Every line item has a job, every job has a price, and the total is a number you chose rather than discovered on a statement.

Audit it monthly. Entry prices are also not forever prices — contact-based lines like Omnisend grow with your list, and that is fine when the list is paying for itself.
