Unit-Based Pricing Explained: Why You Only Pay for What You Monitor
One of the most common frustrations with SaaS tools is pricing that does not match how you actually use the product. You sign up for a plan that gives you 10 of something, you only need 7, but the next tier down only offers 5. So you pay for 10 and waste 3. Or worse, you need 12, and the next tier up gives you 25 at nearly double the price.
At Classifindr, we took a different approach. Our pricing is unit-based, which means your plan is based on the monitoring capacity you actually use. A minimum purchase applies at checkout, and any extra units remain available for other active searches. This post explains how the model works, what units represent, and why we think this is a better fit for marketplace monitoring.
The Problem with Rigid Tier Pricing
Traditional SaaS pricing typically works in tiers: a free tier with limited features, a mid-tier with more capacity, and a premium tier with everything. This model is simple to understand, but it creates several problems for users:
Forced overpaying. If you need 6 searches but the “Basic” plan only includes 5 and the “Pro” plan includes 15, you are paying for 9 searches you do not use.
Artificial limitations. Tier boundaries are arbitrary. There is no technical reason why the basic plan includes 3 notification channels instead of 5; it is a pricing decision designed to push you to a higher tier.
Unpredictable upgrades. You start on a plan that works, add one more search, and suddenly you need to jump to the next tier, doubling your cost for a marginal increase in usage.
Underutilisation. Many users end up on plans where they actively use only a fraction of what they are paying for because the plan is the closest available match to their needs.
For marketplace monitoring specifically, these problems are amplified because monitoring needs vary widely. One person might monitor a single search on one platform. Another might track 20 different items across three marketplaces. A rigid tier system either leaves the first person overpaying or the second person underserved.
How Unit-Based Pricing Works
Unit-based pricing is straightforward: each monitoring action has a unit cost, and your plan is based on your total reserved capacity. Think of it like a utility bill: the bill tracks the capacity you need, while checkout minimums keep the payment flow practical.
In Classifindr’s model, units represent the monitoring resources your searches consume. The main factors that determine your unit usage are:
Number of Searches
Each active search consumes a base amount of units. More searches mean more units, which makes intuitive sense, since monitoring 10 different items requires more work than monitoring 1.
Monitoring Frequency
How often your searches are checked affects unit consumption. A search that runs every few hours uses fewer units than one that runs more frequently. This lets you choose the right balance between responsiveness and cost for each search.
Platform Complexity
Different marketplace platforms require different levels of effort to monitor. Some platforms are straightforward to check, while others require more resources. Unit costs may vary slightly by platform to reflect this reality.
Multi-Platform Monitoring
You can point a single search at more than one marketplace at once. If you monitor two platforms with the same search, its unit cost doubles; three platforms triple it. This is far simpler than creating N copies of the same search, and it keeps all matches for a given configuration in one place.
Practical Examples
To make this concrete, here are a few example configurations and how they translate to unit-based pricing.
Example 1: Casual Buyer
Sarah is looking for a specific model of stand mixer. She sets up:
- 1 search on Facebook Marketplace for “KitchenAid Artisan” in her city
- Standard monitoring frequency
- Email notifications only
This is a lightweight configuration. Sarah uses a small number of units and pays accordingly. When she finds her mixer and pauses the search, her unit consumption drops to zero.
Example 2: Active Flipper
Marcus flips electronics and furniture. He runs:
- 8 searches across Facebook Marketplace and Gumtree (AU and UK)
- Various keywords: “MacBook Pro”, “iPhone 15”, “Herman Miller”, “Dyson”, etc.
- Higher monitoring frequency on high-priority searches
- Telegram and Discord notifications
- Price-based filtering rules
Marcus uses significantly more units than Sarah, but his plan stays tied to the capacity he actively reserves. If he pauses his furniture searches during a slow period, his unit requirement drops, subject to the checkout minimum for his billing cadence.
Example 3: Reselling Business
A small business monitors marketplaces for inventory sourcing:
- 20+ searches across Facebook Marketplace, Gumtree (AU and UK), Craigslist, and OfferUp
- Multiple keyword variations per item category
- Frequent monitoring schedules
- Discord and Telegram alerts for fast team communication
- Advanced filtering rules across all searches
This is heavy usage, and the unit cost reflects that. But the business can choose a plan sized around the capacity it needs. If it scales back to 15 searches during a quiet month, the required unit capacity decreases accordingly.
Why Flexibility Matters
The key advantage of unit-based pricing is that it adapts to your actual usage patterns. Here are the specific ways this benefits different types of users:
Scale Up Gradually
You do not need to commit to a large plan upfront. Start with one or two searches, see how the tool works for you, and add more as you need them. Your cost grows incrementally after the minimum purchase for your billing cadence.
Scale Down Without Waste
Life changes. Maybe you found the item you were searching for, or your flipping season is over. With unit-based pricing, reducing your searches directly reduces your cost. You are not locked into paying for capacity you are not using.
Seasonal Adjustments
Many marketplace shoppers and flippers have seasonal patterns. You might monitor heavily in the lead-up to moving house, then barely use the tool for months. Unit-based pricing naturally accommodates this without requiring you to manage plan upgrades and downgrades.
Per-Search Optimisation
Because each search contributes to your unit total, you have an incentive to optimise. Remove searches that are not producing useful results. Consolidate overlapping searches. Adjust monitoring frequency based on how active a particular market is. This keeps your costs aligned with the value you are getting.
Weekly vs. Monthly Billing
Classifindr offers billing flexibility as well. Depending on your plan, you may have the option to choose between weekly and monthly billing cycles. Weekly billing is particularly useful for short-term monitoring needs. If you only need to monitor for a couple of weeks while searching for a specific item, you pay for those weeks rather than a full month.
Monthly billing offers a simpler cadence for ongoing monitoring and may come with a per-unit discount for the commitment. Choose the option that best matches how you expect to use the tool.
Bonus Units on Larger Packs
We reward commitment with automatic bonus units on larger weekly and monthly packs. The bonus scales up as your pack size grows, and the exact number of bonus units for any pack size is shown directly on that plan’s card on the pricing page. Bonus units land in your account every billing cycle alongside your paid units and behave identically. Pause a search, and both paid and bonus units return to your balance.
What You Do Not Pay Extra For
AI-powered title and thumbnail filtering, description filtering, and advanced rule logic are all included in the base unit cost of a search. There are no per-feature add-ons to enable or upgrade to. Add what you are looking for, and the filtering stack treats AI relevance as a normal part of the search.
How to Estimate Your Needs
If you are new to marketplace monitoring, here is a practical approach to estimating your unit needs:
- Count your searches. How many distinct items or categories do you want to monitor? Each one is a search.
- Choose platforms. Are you monitoring one platform or multiple? Each platform per search adds to unit consumption.
- Consider frequency. How time-sensitive are your purchases? If you are casually browsing, a standard schedule is fine. If you are flipping competitively, you may want more frequent checks.
- Plan notification channels. Most users start with one or two channels, typically Telegram or Discord plus email.
Start with this baseline and adjust as you go. The beauty of unit-based pricing is that you can experiment without committing to a tier you might not need.
Comparing to Traditional Pricing
Here is a simple comparison:
| Scenario | Traditional Tiers | Unit-Based |
|---|---|---|
| Need 6 units, tiers offer 5 or 15 | Pay for 15 (overpay for 9) | Buy 6 units when it is above the cadence minimum |
| Seasonal usage (heavy 3 months, light 9 months) | Pay the same all year | Adjust capacity as usage changes |
| Want to try one extra search | Might trigger a tier upgrade | Marginal unit cost increase |
| Reduce from 10 to 3 units | Still on the same tier | Reduce to the cadence minimum, with extra units available for other searches |
The pattern is clear: unit-based pricing aligns cost with value at every level of usage.
