Twelve-day close to a half-day close. Stacks was a material part of that.

I bought it for automated bank rec and JE upload and assumed I'd ignore the close calendar. The close calendar is one of the best things in it — one view of what's done, what's left, and who owns it, across six subsidiaries in NetSuite OneWorld. The JE upload being Excel-native is the sleeper feature; it effectively gives NetSuite the mass-edit capability it's never had, including for entries Stacks didn't create.

The broader upside is structural. Stacks doesn't make the last days of the close faster. It takes work off the last days entirely, so there's nothing left to compress. Close stops being a special event and becomes a Tuesday. Review collected by and hosted on G2.com.

We were an early customer. That comes with a cost, and the cost is your own time.

Being that early meant we were effectively part of the QA function. New capability arrives, we test it, we find what's broken, and we do that against live close deadlines with a six-person accounting team that has other work. The fixes come back fast — genuinely fast, faster than any vendor I deal with — but the finding is on us.

That trade was worth it for us. We got a product shaped around how we actually close, and a direct line to not only Leadership, but also subject matter specific developers. If you're buying Stacks today you're buying a more finished product and you'll do less of that, which is the correct outcome for you and probably a small loss for you too.

The other thing: the most valuable workflow we run through Stacks is one we invented ourselves, and nothing in the documentation or onboarding pointed at it. There is more in this product than the materials surface. Ask what else it does. Then ask again. Review collected by and hosted on G2.com.

Documentation for monthly closing procedures is kept all in one place, which is super helpful. It makes it easier to build an audit trail and to harmonize processes across different entities, especially when using agents to automate recurring tasks. The product is also easy to onboard to and get started with. Stacks is very open to customization requests; we feel heard, and we’re looking forward to continuing to build a more efficient finance department. Review collected by and hosted on G2.com.

Nothing to dislike. On the contrary, as we require some customizations for our business, Stacks is very open to customization requests; we feel heard, and we’re looking forward to continuing to build a more efficient finance department. Review collected by and hosted on G2.com.

We started the Stacks integration even before we went live with our ERP. The Stacks team was incredibly supportive from the very first conversations, and it’s genuinely a lot of fun working with them. It’s also super impressive to see how quickly the product keeps developing, especially considering we’ve been live for less than a year.

The user interface is very clean, easy to navigate, and self-explanatory. There are many functionalities that make the close faster and smoother, and it’s enjoyable to collaborate with the team in the process. In the meantime, we’ve put AI agents in place, and it’s great to see how they improve over time. The almost instant ERP sync, plus the ability to create payments or JEs in NS without even leaving the Stacks interface, saves us a lot of time and has clearly increased our speed and efficiency.

We’re struggling to match credit card receipts that are submitted late, because Stacks matches them based on the receipt date rather than the accounting date. And so they are missing in the current accounting period matching processes. Review collected by and hosted on G2.com.

An innovative tool that helps streamline the month-end process. It’s currently in a high-growth start-up phase, so there are always new developments, and the team takes customer feedback on board. Integration with NetSuite is, understandably, very good. Review collected by and hosted on G2.com.

Since it’s still growing, there are a few areas it doesn’t handle particularly well yet. The UX is okay, but definitely not the best. It’s also not at a stage where we can use it to post journals and pull data in, so I can’t replace my existing solutions with it. Flux analysis is fine, but it still feels limited to month-on-month only. Review collected by and hosted on G2.com.

UI looks modern and easy to navigate, which simplifies the internal team's training. Plus, the Stacks team were great with onboarding and training as well as ongoing customer support.

The automated matching in the cash reconciliation tool works well with minimal errors made. Review collected by and hosted on G2.com.

To move past the initial rollout stage and drive higher automation, we need enhanced visibility through live stats providing insights into fully automated matching rates, common error trends, accounts with the lowest automation levels, and a breakdown of transactions that consistently require manual intervention.

UI: for a cash rec tool, it needs to be a bit more interactive from the user perspective - more varied sorting and filtering, all pages displaying the checklist/bank rec that the team is working on, live status if others are working on the same account.

Journals: suggested journals for unmatched transactions, drop-downs, and pre-filled suggested info for all journal fields to speed up posting, as the user can currently complete postings faster in NetSuite by copying a previous journal.

The Stacks cash rec tool currently handles matching very well. However, the journaling functionality needs additional work. Because journaling isn't quite there yet, users are slower to fully transition to Stacks—instead, they are combining it with NetSuite, which ultimately diminishes the value-add of the new tool. Review collected by and hosted on G2.com.

I like how Stacks connects really easily to NetSuite. The data flow from the GL to Stacks is seamless, which I find really advantageous. It's ready to go with minimal need for additional input, which saves me a lot of time. The implementation was pretty easy too, as we were live within the first month. The tool was implemented very quickly by the team. Review collected by and hosted on G2.com.

The AI reconciliation agent in Stacks hasn't met expectations. It doesn't allow for two reconciliations for the same account, forcing you to choose, which is restrictive compared to the transaction matching tool that gives more freedom. Also, the AI agent is rigid in proposing journals and doesn't let you pin necessary fields, requiring them to be added manually each time. It's not adept at identifying complex transactions like intercompany transfers. More customization on the flux analytics side would be appreciated. Review collected by and hosted on G2.com.

The excel wizard has drastically saved our team time. We also enjoy the bank recs and checklist (however, these features can be found in a lot of other softwares). The support is 10/10, it's never a struggle to get an answer and anything that does take longer the team are always communicating and looking for a solution. The support makes the product feel bespoke as the team build for us.

In terms of UX/UI we are finding the odd glitch or poor UX/UI but because of the support team these are often fixed very quickly. Our suggestions are taken onboard.

I'm surprised by how well stacks performs with our large data set. At the start when it was struggling the engineer team sorted it so it worked more efficiently.

For how we're using it now, the price is steep, but the team are constantly coming out with new additions such as flux so hopefully when it comes time to renew the contract, it will seem worth the price. Review collected by and hosted on G2.com.

I'm not feeling so far that it's worth the price. While we do get a lot of good capability, I'm not seeing a high ROI on it. For example we paid for a high transaction amount because of paypal, which stacks is not yet capable of helping us with. Review collected by and hosted on G2.com.

The Excel Assistant is easily my favorite feature. It saves me a significant amount of time during our month-end workflows. It is a massive upgrade and much more efficient compared to the old, manual CSV importer we used to rely on. Review collected by and hosted on G2.com.

My biggest frustration with Stacks is their approach to user feedback. We have requested necessary fixes for the tools we use daily, but they do not seem to be a priority for the development team. When a vendor consistently ignores requests to improve their existing features, it feels dismissive and makes us feel undervalued as customers. Review collected by and hosted on G2.com.

Using Stack in our month-end processes at Future PLC has improved significantly, largely because of the efficiency this tool has brought to uploading journals. Review collected by and hosted on G2.com.

At the moment, the integration between product codes and IDs is still being worked out by Stacks in collaboration with our Finance Systems team. This is currently a roadblock and is preventing us from fully utilising the tool. Review collected by and hosted on G2.com.

It has helped our teams identify common errors with their journals before they attempt to upload them into our system - this is has reduced the amount of time spent waiting for the error file to be supplied and the attempts made before the files go through.

The products are shown by name instead of unique ID - this means where some of our data has the same name, employees have to be careful to use the correct one. Review collected by and hosted on G2.com.
