TL;DR: Custom Fields in Quire are user-defined fields (text, number, currency, date, checkbox) that hold the data your tasks need but the built-in properties don't cover. Pair them with Quire's formula engine and your task list turns into a small dashboard: schedule variance, cost-per-task, ROI per campaign, all calculated automatically as the underlying numbers change. Available on every plan including free.
Quire ships with a fixed set of task properties: assignee, due date, status, priority, tags. That covers about 80% of what most teams need. The other 20% is where Custom Fields come in. A marketing team needs a "target audience" tag with structured options. A sales team needs a "deal size" currency field they can sum across the pipeline. An engineering team needs an "estimated hours" field they can compare to actuals. Built-in properties don't cover any of those, and that's the gap.
Two industry references make the point concretely. The PMI PMBOK Guide treats project-specific attribute fields as one of the core configuration assets for any maturing PM tool. Google's Site Reliability Engineering handbook, written for a very different audience, lands on the same principle from a different angle: track the data you actually need for the decisions you actually make, not the data the default form happens to capture.
Let us introduce you to Quire Custom Field - the pièce de résistance of our latest update. Custom Fields are user-defined fields that can be added to tasks to capture additional information.
These fields can be text, numbers, currency, dates, or checkboxes, depending on the information type that needs to be captured. Users can then enter information into these fields when creating or editing tasks.
Here's where the magic truly happens: The Ultimate Quire Formulas. Quire's formula writing is the cherry on top of the Custom Fields cake. Imagine being able to automate calculations, create dynamic analytics, and derive insights on the fly. It's like having a project management wizard right at your fingertips!
Custom Fields enable you to add tailored labels to these tasks, such as "Project Health Indicators," "Target Audience," or even "Budget Allocation." This newfound flexibility means you can organize and sort tasks in a way that makes sense to you and your team, making the project management process more intuitive and efficient.
Now, let's take a closer look at some of the fantastic benefits of using Custom Fields in Quire:
"But how do I actually use Custom Fields in Quire?" We hear you ask. Fear not, my friend – it's incredibly straightforward. In the detail panel of each task, you can click on Add a field and start creating your first custom field in Quire.

Custom Fields is available for every user. More information can be found on our Pricing page.
Most PM tools ship something like custom fields. The differences come down to which data types are supported, whether formulas can compute on them, and what tier you have to be on.
| Tool | Field types | Formulas on fields | Plan tier required |
|---|---|---|---|
| Quire | Text, number, currency, date, checkbox | Yes (full formula engine, runs in fields and descriptions) | All plans including free |
| Asana | Text, number, drop-down, date, people | Limited (formula custom fields on Business+) | Premium and above |
| ClickUp | Wide library (15+ types) | Yes (formula type) | Most types Free; some advanced types Business+ |
| Monday | Wide library (20+ columns) | Yes (formula column) | Standard and above |
| Notion | Wide library, deep database integration | Yes (formula property, Notion Formula language) | Free for basics; team workspace for collaboration |
The pattern: most tools support custom fields at some plan tier; the harder question is whether you can compute on them. Quire's full formula engine on all plans is the unusual part of this row.
With our new Custom Fields feature, we've taken that project management game to the next level. We've gone beyond the basics and added the magic of formulas. Quire Formulas has the most complete formula writing among PMS solutions. So, what makes Quire's formula writing stand out from the crowd?
Our formulas are like the secret sauce that adds a dash of magic to your data. Whether you're tracking budgets, analyzing task completion rates, or forecasting project timelines, our formulas will help you crunch the numbers effortlessly.
Quire's formula writing isn't a one-trick pony. We've packed it with an extensive library of functions that cover a wide range of calculations. From basic arithmetic to complex statistical analysis, we've got you covered.
Say you're juggling tasks across time zones or working with tight deadlines. With formulas, you can automatically create the schedule variances for each task by the following formula:
{Time Spent} - estimated
Imagine you've got two fields up and running: one tracks the Time Spent on each task, while the other records the Budget Per Hour. Now, let's say you're itching to compute the total budget required for each task, using the data from these two fields. Here's how the magic happens:
{Time Spent} * {Budget Per Hour}

You're in for a treat because the Quire Formula writing isn't limited to just task-related calculations. You can take it up a notch by applying it to your Project Overview or even task descriptions, essentially crafting a dynamic dashboard right within your project.
Imagine this: your Project Overview comes to life with real-time updates, displaying calculated values that keep you in the loop about progress, resource allocation, or any other metric you need.
And the best part? It's not a static display; it's fully interactive. So, as your project evolves, your dashboard adapts, providing you with an ever-current snapshot of your project's health and performance.
Even if you’re no Excel or SQL guru, the Quire formula writing interface is designed with simplicity in mind. Our formulas adapt to your project's unique structure, allowing you to create tailor-made calculations that fit your specific requirements.
Though Quire Custom Fields is a powerful feature, it might be confusing for our first-time users. Here are some scenarios that we use Custom Fields here at Quire. You can be creative but these scenarios are a good place to start!

Our Event Manager needs to work with the team on various campaigns. They need to keep track of various parameters like campaign start dates, target demographics, budget allocations, and more.
With Custom Fields, we effortlessly create fields like "Duration", "Target Demographics" using text or selection, and "Budget" using currency type. Then we associate these new fields with specific tasks or projects. This way, we can easily access and update these critical details whenever needed, saving time and ensuring nothing falls through the cracks.

Data analysis isn’t always the happiest and easiest job in the world. However, Custom Fields in Quire open up new possibilities for tracking progress and analyzing data in the task list.
The Business team can define custom fields that align with the performance indicators or metrics, then use the customized formulas to easily evaluate the success of the projects and make informed decisions based on accurate data.
For instance, with each dollar invested in Google Ads, the team needs to track the ROI that each ad generates. By creating a custom field using a simple division math formula (NET Revenue/Cost of Investment), the team can record and make necessary adjustments accordingly with this data at their fingertips.
Open any project in Quire, pick a task, click Add a field in the detail panel, and pick the field type that matches the data you want to capture. Start with one field on one project. Most teams add three or four within the first month once they see how Custom Fields surface data that used to live in task descriptions or a separate spreadsheet.
Custom Fields are available on every Quire plan, including free. The pricing page covers plan-tier limits on advanced formula functions.
